TChart Numeric Gauge

[Mobics]

I have a question about TCharts Numeric Gauge.
No matter what theme or pallete I choose, after compiling and running the program, the gradient on the back is always returned to his standard 'green'-white gradient.
The GUI designer in delphi does show the gradient correctly.

Hi,

No matter what theme or pallete I choose, after compiling and running the program, the gradient on the back is always returned to his standard 'green'-white gradient.

The gauges are quite special series that don't use the regular axes or walls. That's why the themes don't work as with the other series types.

The GUI designer in delphi does show the gradient correctly.

I don't see it and I'm not sure the themes/palettes ever applied to the numeric gauge.
What version are you using? Could you please explain what exact steps we could follow to reproduce it here?
A screenshot could help here.

I'm using version TeeChart Pro v2012.06.120613 32bit VCL.
Create like this:
Add TChart -> Add Series: gauges: 'Numeric Gauge' -> then open the gauge.
Tab 'Format' -> there tab 'Back' -> there tab 'Gradient' and there I create a different Gradient.

Left is compiled, right is designer.

Hi,

You're right. It seems the properties set at designtime in the Gradient tab aren't correctly serialized.
I've added it to the wish list to be revised for future releases (TV52016362). In the meanwhile, you could set them at runtime. Ie:

Code: Select all

    Series1.Face.Gradient.Visible:=false;

Or:

Code: Select all

    Series1.Face.Gradient.StartColor:=clBlack;
    Series1.Face.Gradient.MidColor:=clGrayText;
    Series1.Face.Gradient.EndColor:=clBlack;

I will try this later.

I also found a problem for the linear gauge. It looks like it doesn't save the Bottom Axis Title (at least: after compiling it stil says 'Axis Title %') and on the other moment it is even changed back to this in designer mode.

Working correctly with your solution.
I'm also doing this with the text in de LinearGauge

Hi Mobics,

I've added this to the wish list too (TV52016365).

I'm glad to hear the workaround works fine for you
