Cannot assign new Title to streams of a UniChart

Then just set a large number, for example 1000 instead of 50.

For example:

UniChart.ClientEvent.UniEvents -> 

function chart.beforeInit(sender, config)
{
    config.series[0].renderer = function(a) {
          a.attr.maxBarWidth = 1000;
          a.attr.minGapWidth = 20;
          a.attr.inGroupGapWidth = 5;
          return a
    };
}

Youre right, simply setting a large number for MaxBarWidth as the default value is the easiest solution!

Thanks

In another thread you gave the following solution for hiding the legend that appears inside very pie:

UniChart ("PieChart")-> ClientEvents -> UniEvents -> function chart.beforeInit:

function chart.beforeInit(sender, config)
{
    config.series[0].renderer=function(sprite, config, rendererData, index){
        return {label: ""}
    }
}

But when I do this, I get an error:
Cannot read properties of undefined (reading '0')

 

Is there a way that I can do this via a JSCall()?

 

This is what I need, just the pie chart without the lines and label on the  border

Hello @Woutero

Because you're doing it wrong.

[Woutero]

Sherzod

Thank you, that works!

Is there a way that I can do this via a JSCall() so that I can switch between hide/display during runtime?

[Sherzod]

I will try to check.

One possible solution:

1. 

function chart.beforeInit(sender, config)
{
    config.series[0].renderer=function(sprite, config, rendererData, index){
        return {label: ""}
    }
}

2. 

3. UniChart.ClientEvents.ExtEvents ->

function afterrender(sender, eOpts)
{
    sender.chart.series[0].setLabel({display: 'none'});
}

4. Runtime ->

procedure TMainForm.UniButton1Click(Sender: TObject);
begin
  UniChart1.JSInterface.JSCall('chart.series[0].setLabel', [UniChart1.JSInterface.JSStatement('{display: "outside"}')]); //none
end;

Thanks Sherzod!

Can you explain the typical workflow or process where users might encounter the issue of being unable to assign a new title to streams in a UniChart?

Hi Sherzod

How can I display the values within a Bar of a uniBarSeries?

I want to display the xxx values, e.g. 35 for bar 1.

[Woutero]

Resolved by using SeriesLabel->Enabled = true

So I can now display the labels, but I cannot display them horizontally.

 

 

The same question was asked here:

 

[Woutero]

Resolved by using ThisChart->JSInterface->JSCall("chart.series[0].setLabel",("{orientation: \"horizontal\"}"));
