label.new(bar_index, high, text=info, xloc=xloc.bar_time, yloc=yloc.abovebar
Your code is full of error.
For the range problem, just change :
range = high - low
To :
myrange = high - low

I have an object constructor that sets some properties, and later uses them to concatenate a string to write to the DOM. I can see that this works in some cases, but not in others.
function Fighter(name, level, attackPts, defencePts, imgSource) {
// TRUNCATED PROPERTY ASSIGNMENTS AREA:
this.attackPts = attackPts;
this.defencePts = defencePts;
// DOM ELEMENT CONSTRUCTORS:
this.img = "style='background: #444 url(" + imgSource + ") no-repeat center'";
this.char_card_name = "<h3>" + this.name + "</h3>";
this.char_card_hitdef = "<h4>" + this.attackPts + "/" + this.defencePts + "</h4>";
this.char_card = "<div class='fighter " + faction + "' " + "id='" + this.name + "'>" + this.img + this.char_card_name + this.char_card_hitdef + "</div>";
In a game function later on I modify the attack and defense points for this "Fighter" object, and that works as expected, and my console.log() tests verify that the concatenated properties also update . . . . up until the final string to pull it all together and display:
this.char_card = "<div class='fighter " + faction + "' " + "id='" + this.name + "'>" + this.img + this.char_card_name + this.char_card_hitdef + "</div>";
When I log this property, those attack and defense numbers don't budge, even though they update successfully in the previous property, this.char_card_hitdef
What could I be overlooking here? I crawled all over the web looking for scope or variable reference issues, but my log statements bring me right back to this one pinching point.
Because you are still in the constructor, you need to refer to the variables without this. that are a parameter AND property of the Object Fighter.
So change
this.char_card = "<div class='fighter " + faction + "' " + "id='" + this.name + "'>" + this.img + this.char_card_name + this.char_card_hitdef + "</div>";
to
this.char_card = "<div class='fighter " + faction + "' " + "id='" + name + "'>" + this.img + this.char_card_name + this.char_card_hitdef + "</div>"
And all other properties that refer to properties above them.

The purpose is to have 2 lines of text on the X axis for each bar.
e.g
JUN
2018
and style each line in a different way ( like color the year label in green ) .
Can we do it?
This is how I populate the bars in a custom way.
str += '<set label="' + months[i].toUpperCase() + ' ' + currentyear + '" value="' + amount + '" color="08cf77" toolText="' + cur_symbol + amount + '" />\n';
Simply use
'
'
So the line should be updated as;
str += '<set label="' + months[i].toUpperCase() + '
' + currentyear + '" value="' + amount + '" color="08cf77" toolText="' + cur_symbol + amount + '" />\n';
I have integrated SQLite.swift framework in one of my swift project and everything was working fine until i added the below query. After adding the below query project is taking too long to build. I waited for 30 mins but still project is n't complied.
do
{
let stmt = try DB!.prepare ("SELECT e." + ENDPOINT_ID + " as _id, lk." + HUB_ID + ", e." + X_ENDPOINT_ID + ", e." + ENDPOINT_DESC + ", e." + ENDPOINT_TYPE_ID +", et." + ENDPOINT_STATUS_MIN + ", et." + ENDPOINT_STATUS_MAX + ", e." + ENDPOINT_STATUS + " FROM " + TABLE_ENDPOINT + " as e INNER JOIN " + TABLE_ENDPOINT_TYPE + " as et " +
" ON e." + ENDPOINT_TYPE_ID + " = et." + ENDPOINT_TYPE_ID +
" INNER JOIN " + TABLE_LINKING + " as lk " +
" ON e." + ENDPOINT_ID + " = lk." + ENDPOINT_ID +
" INNER JOIN " + TABLE_NODE + " as n " +
" ON lk." + NODE_ID + " = n." + NODE_ID +
" INNER JOIN " + TABLE_NODE_TYPE + " as nt " +
" ON n." + NODE_TYPE_ID + " = nt." + NODE_TYPE_ID +
" WHERE lk." + SECTION_ID + "=" + section_Id +
" AND nt." + NODE_CATEGORY + " = "S" " +
" ORDER BY e." + ENDPOINT_ID + " ASC")
let arr = Array(try stmt.run)
print("\(arr)")
return arr
} catch {
print("failed: \(error)")
return []
}
If i comment the above code and try to run the project it takes hardly a minute to run the project but after adding this code, it's taking hell lot of time. I have waited for almost 30 mins but still the project is not compiled nor it's throwing any error.
Thanks in advance for help
The Swift compiler has difficulties to deal with big string literals. See also this question for further hints.
I would recommend to split up the sql and to build a string variable in small steps:
var sql = "SELECT e." + ENDPOINT_ID
sql = sql + HUB_ID + ", e."
sql = sql + X_ENDPOINT_ID + ", e."
...
let stmt = try DB!.prepare(sql)
let query = (TABLE_ENDPOINT.select(TABLE_ENDPOINT[ENDPOINT_ID], TABLE_LINKING[HUB_ID], TABLE_ENDPOINT[ETCT_ENDPOINT_ID], TABLE_ENDPOINT[ENDPOINT_DESC], TABLE_ENDPOINT[ENDPOINT_TYPE_ID], TABLE_ENDPOINT_TYPE[ENDPOINT_STATUS_MIN], TABLE_ENDPOINT_TYPE[ENDPOINT_STATUS_MAX], TABLE_ENDPOINT[ENDPOINT_STATUS]).join(TABLE_ENDPOINT_TYPE, on: TABLE_ENDPOINT[ENDPOINT_TYPE_ID] == TABLE_ENDPOINT_TYPE[ENDPOINT_TYPE_ID]).join(TABLE_LINKING, on: TABLE_ENDPOINT[ENDPOINT_ID] == TABLE_LINKING[ENDPOINT_ID]).join(TABLE_NODE, on: TABLE_LINKING[NODE_ID] == TABLE_NODE[NODE_ID]).join(TABLE_NODE_TYPE, on: TABLE_NODE[NODE_TYPE_ID] == TABLE_NODE_TYPE[NODE_TYPE_ID])
.filter(TABLE_LINKING[SECTION_ID] == section_Id && TABLE_NODE_TYPE[NODE_CATEGORY] == "S")
.order(TABLE_ENDPOINT[ENDPOINT_ID].asc))
let arr = Array(try DB!.prepare(query))
I have code that will search particular fields in the document to find the values that the user selects and places those documents in a folder. I have the code working, but I'm stuck on how to proceed with doing the same thing with date fields. I need to be able to find documents within a date range.

You can use operators = / < / > / <= / >= for date fields in FTSearch.
Example: FIELD YourDateField > 01/30/2013 or [YourDateField] > 01/30/2013.
To find documents within a date range you'd write:
[YourDateField] >= 01/01/2013 AND [YourDateField] <= 12/31/2013

I am using wicket 1.5 and I am not able to see in the getClientInfo() method
(WebRequest)RequestCycle.get().getRequest()
I saw the other place this code
WebClientInfo clientInfo = (WebClientInfo)WebRequestCycle.get().getClientInfo();
But I am not able to see any WebRequestCycle in Wicket 1.5.
Any ideas how to check the user agent in Wicket 1.5?
The easiest way is to use
WebSession.get().getClientInfo().getUserAgent();
On newer Wicket Versions (6 or newer), you should use:
WebClientInfo clientInfo = new WebClientInfo(getRequestCycle());
System.out.println("Client: " + clientInfo.getUserAgent());
System.out.println("Navigator: " + clientInfo.getProperties().getNavigatorAppName() + ", version " + clientInfo.getProperties().getNavigatorAppVersion() + ", codName: " + clientInfo.getProperties().getNavigatorAppCodeName() + ", plataform: " + clientInfo.getProperties().getNavigatorPlatform() + ", AppCodName: " + clientInfo.getProperties().getNavigatorAppCodeName());
System.out.println("NavigatorUserAgent: " + clientInfo.getProperties().getNavigatorUserAgent());
System.out.println("Tamanho da tela (Width x Height): " + clientInfo.getProperties().getScreenWidth() + " x " + clientInfo.getProperties().getScreenHeight() );
You can also do:
((WebRequest) getRequest()).getHeader("User-Agent")
