I've taken the example code, and am playing with the chart. I want to set the background color of the chart to white.

I've commented out the 'gradient' part, but can't see how to change the panel background color. I get an error (even though this is in the help files in the installation):


Microsoft VBScript runtime error '800a01b6'

Object doesn't support this property or method: 'Panel.BackWallColor'


Obviously missing something silly here!!!!


Thanks.

Hello Keith,

You only need change the color of panel as I do using next code: Could you please tell us if previous code works in your end?

I hope will helps.

Thanks,

Hi Sandra.

That worked fine. Thanks.

I have a second issue on the same chart. The 'actual' series value (which is being set as rgb(0,255,0) ) is showing as Green in the chart itself, but in the Legend, it's an amber/orange color.

Any ideas please?

Full code below - thanks.

Hi,

Note you can ser a color to a series but also to each point in that series. And it's actually what you are doing when adding the points with value, label and color.
Since you haven't set the series' color, the colors of the default palette are taken as the series colors, and so is shown in the legend.
You can set the series' color, ie assigning the color you have in the first point of the series. And the same for the three series.

Thanks - that worked great. Think I''ll need to spend time looking at the tutorials....

Always recommended. I'd also suggest you to take a look at the features demo to see the possibilities of the component.
