(I'm using GWT, which wraps javasciprt / html, so think it applies here as well).
I'd like to use a color with varying opacity on a canvas element. It looks like I have to keep creating a CssColor over and over again as there is no setOpacity() method that I can see:
// fade in
for (int i = 0; i < 255; i++) {
CssColor clr = CssColor.make("rgba(" + 255 + ", " + 0 + "," + 0 + ", " + i + ")");
canvas.setFillStyle(clr);
canvas.fillRect(...);
}
Is there any way to just modify the alpha value on a constructed color, rather than creating all these new objects?
Thanks
You can use setGlobalAlpha(double alpha)

for my Thesis I must count cells on pictures stained with Immunofluorescence and I am writing a macro in ImageJ to do it for me.
For this I coloursplit the picture, analyse particles in the red channel (my Antibody´s colour) and then I want to take the coordinates of analysed particles and only count them if at the same coordinates in the blue channel there is also a staining (DAPI - just a general cell staining).
This way I assure that there is as little dirt counted as possible.
The problem is that when I get the coordinates from the results table and use them to makePoint(x,y) the coordinates are "distorted" - usually the correct coordinates but plus 4ish, though never in exactly the same, which is why i can´t simply distract a number from the coordinates
Below I first write down the critical lines of code, then the whole code.
Thank you very much in advance

Could someone suggest the right way to eliminate constants from the code in production mode? I've already tested babel-plugin-constant-folding and babel-plugin-dead-code-elimination but they both work only with babel 5, not with babel 6.
Example:
const K=1;
const B=K + 13;
console.log("b=" + B);
I expect to get:
console.log("k=" + 1 + ", b=" + 14)
or, better (honestly, I don't need this level of optimization, replacing all ID with their values without string concat is completely enough for me):
console.log("k=1, b=13")
but get only:
var K = 1,
B = K + 13;
console.log("k=" + K + ", b=" + B);
Could someone suggest me the right sequence of babel plugins?
I've been trying for days to create charts with an intelligent range, that differs when the data in the google spreadsheet is updated. However i succeeded doing so, i can't get the .setOption aspect to work. I want for example, a title, description etc with the chart. But this is not the main issue since i can insert there by hand.
More important however is the range name, because there isn't when i use the script. So, within the chart it is not possible to see what each column represents, and i really want to fix that. I tried to use the .setNamedRange() aspects, but that is not working.
Someone who can help me with that?
function check() {
var sheet = SpreadsheetApp.getActiveSheet();
var end = sheet.getLastRow();
var start = (end - 5);
var endnew = (end - 4);
var startnew = (end - 6);
if(sheet.getCharts().length == 0){
Logger.log("Er is geen grafiek");
var chartBuilder = sheet.newChart()
.asColumnChart().setStacked()
.addRange(sheet.getRange("A" + startnew + ":" + "A" + endnew)) // should have a name
.addRange(sheet.getRange("B" + startnew + ":" + "B" + endnew)) // should have a name
.addRange(sheet.getRange("E" + startnew + ":" + "E" + endnew)) //should have a name
.setOption('title', 'Effectief gebruik kantoorruimte') //not working
.setPosition(10, 10, 0, 0)
var chart = chartBuilder.build();
sheet.insertChart(chart);
}
else{
Logger.log("Er is wel een grafiek");
var charts = sheet.getCharts();
for (var i in charts) {
var chart = charts[i];
var ranges = chart.getRanges();
var builder = chart.modify();
for (var j in ranges) {
var range = ranges[j];
builder.removeRange(range);
builder
.addRange(sheet.getRange("A" + (start) + ":" + "A" + end)) //should have a name
.addRange(sheet.getRange("B" + (start) + ":" + "B" + end)) //should have a name
.addRange(sheet.getRange("E" + (start) + ":" + "E" + end)) // should have a name
.setOption('title', 'Effectief gebruik kantoorruimte')
.build();
sheet.updateChart(builder.build());
}
}
}
}
I'm assuming that this code is the issue?
builder
.addRange(sheet.getRange("A" + (start) + ":" + "A" + end))
Maybe try using the JavaScript toString() method to make sure that your text formula is working.
.addRange(sheet.getRange("A" + start.toString() + ":" + "A" + end.toString()))
There is a different format that you can use:
getRange(row, column, numRows, numColumns)
So, it would be:
getRange(start, 1, 1, numColumns)
That starts on row "start" in column A. It gets one row of data, and how ever many number of columns.
I am trying to find out how to do the Progress equivalent of a "GROUP BY" function. I am trying to write a procedure that will list product inventory information for multiple locations. Right now, it is listing the product information twice; once for each location. I have tried the BREAK BY functional unsuccessfully. My current & desired output and code is below:
Current Output:
Desired Output:
DEF INPUT PARAMETER ip-um AS CHARACTER NO-UNDO.
MESSAGE
"ProdCode" + "^" +
"ProdName" + "^" +

SKIP.
FOR EACH product-um WHERE
product-um.gross-pkgd-weight <= 0.0000
NO-LOCK,
EACH product WHERE
product.product-key = product-um.product-key AND
product.can-be-sold = YES
NO-LOCK,
EACH inventory WHERE
inventory.product-key = product.product-key AND
inventory.qoh > 0 AND
inventory.level = 2
NO-LOCK,
EACH um WHERE
um.um-key = product-um.um-key AND
um.um = ip-um
NO-LOCK
BREAK BY product.product-code:

SKIP.
END.
because you accumulate invesntory.qoh in dependency of inventory.level-key-2 the ACCUMULATE stmt is not realy feasible so coding the accumulation manually would be the best choise
DEFINE VARIABLE loc1 AS INTEGER NO-UNDO.
DEFINE VARIABLE loc2 AS INTEGER NO-UNDO.
FOR EACH product-um NO-LOCK
WHERE product-um.gross-pkgd-weight <= 0.0000
,
EACH product NO-LOCK
WHERE product.product-key = product-um.product-key
AND product.can-be-sold = YES
,
EACH inventory NO-LOCK
WHERE inventory.product-key = product.product-key
AND inventory.product-code = product.product-code
AND inventory.qoh > 0
AND inventory.level = 2
,
EACH um NO-LOCK
WHERE um.um-key = product-um.um-key
and um.um = ip-um
BREAK
BY product.product-code:
CASE (inventory.level-key-2):
WHEN "00000001"
THEN loc1 = loc1 + inventory.qoh.
WHEN "00000002"
THEN loc2 = loc2 + inventory.qoh.
END CASE.
IF LAST-OF(product.product-code)
THEN DO:
MESSAGE
product.product-code + "^" +
product.product-name + "^" +
um.um-code + "^" +
STRING(product-um.gross-pkgd-weight) + "^" +
STRING(loc1) + "^" +
STRING(loc2)
SKIP.
ASSIGN
loc1 = 0
loc2 = 0
.
END.
END.
BREAK BY tells the compiler to mark when the FOR EACH has come to the start or end of a break group.To detect these changes you'll need to use one of these functions to detect that change: FIRST(table.field), FIRST-OF(table.field), LAST(table.field), and LAST-OF(table.field).
Once the required function returns true, you can use the ABL supplied functions like ACCUMULATE, COUNT, TOTAL, etc. to display the desired results. Personally I find the concepts a bit hard to get my head around, so I declare some local variables and do the totals that way.
Using Highstock, I've a serie timestamp / value
with different rangeselectors (hour, day, week, month,...) or zoomX
I want to display the average value for the displayed time period.
Now, I can compute the average of the overall series data:
for (i = 0; i < chart.series[0].yData.length; i++) {
total += chart.series[0].yData[i];
}
seriesAvg = (total / chart.series[0].yData.length).toFixed(4); // fix decimal to 4 places
$('#report1').html('<b>Average:</b>: '+ seriesAvg);
How to compute the average only on the displayed datapoints ? And to refresh automatically after zoom ?
Thank you
Use series.processedYData or series.points.
I implemented the same but I notice that processedYdata is loading also one data more than the one showed at the screen.
for that reason i added one additional command to remove the first processedYData:
processedYData.splice(0, 1);
below is the final result of the function
function showStat(objHighStockchart) {
for (j = 0; j < (json_data.length); j++) {
var seriesAvg = 0,
processedYData = objHighStockchart.series[j].processedYData;
processedYData.splice(0, 1);
var seriesMin = Math.min.apply(null, processedYData);
var seriesMax = Math.max.apply(null, processedYData);
var i = 0
var total = 0;
console.log(processedYData);
for (i = 1; i < processedYData.length; i++) {
total += processedYData[i];
}
seriesAvg = (total / processedYData.length).toFixed(2); // fix decimal to 4 places
$('#container_stat' + j).html(
'<br>Statistics for ' + objHighStockchart.series[j].name + '<br>' +
'Total: ' + total + ' logs<br>' +
'Min: ' + seriesMin + ' logs<br>' +
'Avg: ' + seriesAvg + ' logs<br>' +
'Max: ' + seriesMax + ' logs<br>'
+ '---' + processedYData
);
}
};
