I currently have a map loaded, and I have some bars on the map. I would like to include my variable text_toltip[i] in the tooltip so that the coordinates and text of the variable text_toltip[i] are displayed in each bar. how can I do it? I'm new in this library.
I know that there is an attribute called minHeight, which allows to establish a minimum height for the bars, but I would like to establish a maximum predetermined size for the bars and so the other sizes and colors of the bars are calculated. how can I do it?
series: [{
type: 'bar3D',
coordinateSystem: 'geo3D',
barSize:0.05,
minHeight:0.05,
data: data.map(function (item) {
return {
value: [item[0], item[1], item[2]],
label: {
show: false
}
}
}),
shading: 'lambert'
}]

Thank you.
For this question,I read the Echarts's documentation and found a property belonging to "geo3D called "boxHeight" ,which can play the same role as you say "maxheight".I've tested it,no problem.

How can I exclude a specific data series from showing in the tooltip with tooltip.trigger = axis?
I'm asking because I have a very complex graph with one line chart, two bar charts and one heatmap. And the heatmap has so many data that the tooltip ends up with too many lines. The heatmap values are not very important, so I would like to remove them from showing in the tooltip.
Right now I'm using formatter to exclude them, but is there any other way?
I do exactly the same: adding a new attribute to the series and checking it from formatter.
Something like this:
series: [{
// ...
showInTooltip: true
// ...
}]
// ----
formatter: series => {
var displayed = series.filter(item => item.showInTooltip);
// work with displayed where showInTooltip === true
}
Also you can store callback instead attribute and it will work.
Updated: Suddenly I found undocumented feature and it will solved you trouble by the right way, apparently.
series: [{
// ...
tooltip: {
show: false
}
// ...
}]
I am trying to make a bar chart with VizFrame. Right now this is what my chart looks like:
**edit Chart wont embed? Here is the link: https://imgur.com/5vDzgCs
How would I go about putting the data label inside the bar if it can fit? I tried looking it up, but I am having trouble solving this issue.
Thanks!
to display the data labels inside the bars use the plotArea.dataLabel.position property. As stated in the documentation the property has the following features:
Supported Value Type: String
Supported Values: inside, outside, outsideFirst
Readonly: false
Serializable: true
Default value: "outsideFirst"
Description: Set data label display
position. 'outsideFirst' means if the plot has no space to display data
label outside of the bar, the data label will be displayed inside.
one option to set the property would be for example in the onInit method of the controller of the view:
...
onInit: function() {
oVizFrameBar = this.byId("idVizFrameBar");
oVizFrame.setVizProperties({
plotArea: {
dataLabel: {
position: 'inside'
}
}
}
}
...
I would like to ask how can I position bottom labels using ChartJS library to display them like on the image below:
I tried to find it in official docs, but without the luck.
Many thanks for any advice.
In the xAxe ticks attribute, you can edit the userCallback property to change what is displayed on your labels. Furthermore, if you return an array of strings, every string will be displayed with line breaks.
So if you combine these two informations, you'll get the following :
options: {
scales: {
xAxes: [{
ticks: {
userCallback: function(tick, value, ticks) {
// `ticks` is the default display
// `.split("")` makes it an array of every character
return tick.split("");
}
}
}]
}
}
You can see a working example on this jsFiddle and here is its result :
I need to create a pie chart with labels indicating what each area means, but also another info overimposed over each area. If I use both data labels and a legend, they'll show the same text. How can I have both with different texts, or emulate that effect?
A mock of what I'd like to get:
Using the format or formatter config properties of the dataLabels, you can make them say whatever you want.
pie: {
dataLabels: {
enabled: true,
formatter: function(){
return 'Y Value: ' + this.y; // y value
}
},
showInLegend: true
}
Quick example.
I'm using the following piece of code to display a set of bar charts in jqPlot. However, I am getting 2 problems:
There is no padding on either side of the range values for the xaxis. The pad attribute seems to have no effect.
When the number of bars is large, the bars overlap on top of each other. The barPadding attribute seems to have no effect.
I looked at this link Having problems with jqPlot bar chart . The answer suggested there was to use a CategoryAxisRenderer. But since I'm using time-series data, I require the DateAxisRenderer.
Please help.
function plotBarGraph(data,myticks,series)
{
$("#placeholder").empty();
$.jqplot('placeholder',data,
{
//stackSeries:true,
seriesDefaults:{
renderer:$.jqplot.BarRenderer,
barMargin:1,
barPadding:0.5
},
axes:
{
xaxis:
{
ticks:myticks,
tickInterval:10,
renderer:$.jqplot.DateAxisRenderer,
pad:2.5,
tickOptions:
{
formatString:'%d-%m-%y'
}
}
},
legend:
{
show:true,
labels:series
}
});
}
In this case if you do not want to use the approach mentioned in the link, you might want to play with min/max values for your date axis.
I think you might also find useful the approach to a similar sort of problem with padding where I chose to set ticks on creation and hide the unwanted ones after the plot is drawn.
Before I can be of any further assistance please provide a sample presenting your problem.
For your second problem, I ran into a similar issue. I set up a selection statement that widened the size of my chart depending on how many bars would be in it. I then made the parent div scrollable (called "dataHolder"), and that solved the problem.
// set div properties depending on how many sets of data are in the
//array so the view is sized properly
$("#chartDiv").html("").css("width", "750px"); // chartDiv's default settings
$("#tabs-6").removeClass("dataHolder").css("width", "900px"); // parent Div's default settings
if (dataArray.length > 10) {
$("#chartDiv").css("width", "1600px");
$("#tabs-6").addClass("dataHolder").css("width", "900px");
} else if (dataArray.length > 6) {
$("#chartDiv").css("width", "1200px");
$("#tabs-6").addClass("dataHolder").css("width", "900px");
}
I found a solution to use Date data with CategoryAxisRenderer. You have to configure de xaxis like follows:
axes: {
xaxis: {
renderer: $.jqplot.CategoryAxisRenderer,
rendererOptions: {
tickRenderer: $.jqplot.DateTickRenderer,
tickOptions: {
formatter: $.jqplot.DateTickFormatter,
formatString:'%d/%m'
}
}
}
}
I hope it helps! ;)
