I have encountered a problem switching themes at run-time. It can be illustrated with the demo program:

1. Select the "Chart Themes" group.

2. First, select the "BlackIsBlack" theme.

3. Select the "Facts" theme. Now, the legend text/marks label text is not visible.

4. Select the "BlackIsBlack" theme again.

5. Legend text is now visible again, but not the marks label text, but the chart background is not black!

So, how can one "reset" all colors/settings to the default before applying a new theme?

Hi wiggum,

I've seen that some of themes change the marks/legend color or gradient while other themes don't so they changing from one theme to another, may cause a theme to use marks/legend properties set for another.
I've added it to the wish list to be revised in future releases (TV52015154).

Of course you always can manually enable/disable marks/legend gradient, the GridBandTool added in the Facts theme,...

The inability to "un-apply" or reset a theme is a serious problem that substantially reduces the utility of this otherwise valuable feature.

Some notes:

* Choice of some themes appears to set some properties that are not set by other themes. Some examples:

* "Facts" sets back wall to alternating horizontal bars (like green bar paper, but in grey and white)
but this is not cleared by any other themes

* "Classic", "BlackIsBack", "Blues" set legend color but some others do not, so it leaves setting in place
from previous theme

* Not clear what properties are being set by application of themes, so it's a challenge to determine how to set some properties of certain objects after a theme has been applied. Example:

* "Business" (but not some others) sets back wall transparency to "true",
so subsequent attempts to set back wall color with
a simple assignment of color will fail

These problems make the ChartThemeSelector extremely problematic at runtime. The user can't just try out different themes because each trial leaves artifacts not cleared by the next attempt.

ChartThemeSelector needs a few other tweaks as well:

* One of the available themes is "TeeChart Default". The user shouldn't be seeing the "TeeChart" name.

* The "Color palette" popup doesn't appear to do anything.

* It appears that the purpose of the "Scale" checkbox is purely to be able to better observe
what the effect of the theme is upon the chart while this dialog is in use, without affecting
the chart itself. Correct? If so, the label "Scale" seems inadequate to explain this to the user.

Thank you for considering this!

Hello Kevin Killion,

I inform you that I have increased priority of the wish number ( TV52015154).

On the other hand, I could not reproduce this:

The "Color palette" popup doesn't appear to do anything.

Could you please, explain us exactly which steps we are following for reproduce this problem?

Thanks,
