how to do a donut with percentage inside?

[tecsidel]

Hi,
I have seen a couple of screens you've published, and noticed a dashboard with a donut with percentage in the middle.

Also I don't find how to make these percentages with different sizes with the map series.

To get you started, you can find a similar example here.

Also I don't find how to make these percentages with different sizes with the map series.

The three examples can be easily done, all of them have been done at design time, by using the Chart Editor. First of all, you have to set the Flat theme for the Chart, and the Android palette, this will make to change the chart aspect considerably.
Then, in the case for the Donut series example, you have to specify the hole percent as desired, and add an Annotation tool, which you can position it wherever you want inside the Chart bounds (for example at the hole center), setting a specific font size and family.

Also I don't find how to make these percentages with different sizes with the map series.

About the Map example, as others I used the Chart editor, with map series, adding some Annotation tools to the Chart, setting its position, and font size for each. Although, this can be make by code, specially the case that the annoation size is suposed to change depending on the data.

About the horizontal bar example, I used the Flat theme again, but this time I used a custom color palette, setting each bar color by my own, and change some Chart aspect properties at design time, like pens, fonts, axis, etc.. I've attached the vcl sample to a this post (almost all done at design time).
