[CLOSED] Update chart color set

[bayoglu]

Hello,

I am using custom color set for charts and setting them as below in code behind. MyColorSet is array of strings.

(MyChart.Series[0] as PieSeries).ColorSet = MyColorSet;

Above code works fine during page load. When I re-load chart store with different values, I need to change the color set if necessary. By the way, the chart color set is not updated with above code during server side ajax call (direct method). Do you have a suggestion on the issue?

Thanks.

Hi @bayoglu,

I think such a change requires redrawing a chart. Please try:

Chart1.Redraw();

Hello Daniil, thanks for your support. I already tried .Redraw() with no change. I could make it work as below. Do you have a suggestion on this?

Thanks.

                if (X.IsAjaxRequest)
                {
                    MyChart.Set("assignedColors", MyColorSet);
                    MyChart.AddScript("{0}.series.items[0].colorSet={0}.assignedColors;", MyChart.ClientID);
                }
                else
                {
                    MySeries.ColorSet = ResidualGaugeColorSet;
                }  
                MyChart.Series.Add(MySeries);

You are right.

A bit easier, you can replace

MyChart.Set("assignedColors", MyColorSet);MyChart.AddScript("{0}.series.items[0].colorSet={0}.assignedColors;", MyChart.ClientID);

with

MyChart.Set("series.items[0].colorSet", MyColorSet);

But redrawing is required, anyway.

Hi Daniil,

Thanks for the shortcut. You saved an extra custom config for me (; Please mark as closed.
