Themes - font size issue

[Anonymous]

I have a dozen of matrix tables in several reports. I am not satisfied with the font its have (not looks good).

My idea is to use Themes to change a font size in all my reports.

I downloaded a json file template from:

https://github.com/deldersveld/PowerBI-ThemeTemplates

Then with Switch/Import Themes option in Power BI Destop tried to implement this theme on my test matrix. 

The result is some other formatting attributes changed but not a font. In any place like column headers, rows and values font stayed as in original format.

Do not know why. What is a reason, what is wrong here?

Hi @Anonymous,

Please add a "fontFamily" parameter if needed. Reference: power-bi/desktop-report-themes.

"fontFamily": "Cambria"

This is what I use:

{ 
    "name": "Presentation", 
    "dataColors": ["#000000", "#000000", "#000000", "#000000", "#000000", "#000000", "#000000", "#000000", "#000000", "#000000", "#000000", "#000000"],
    "background":"#FFFFFF",
    "foreground": "#000000",
    "tableAccent": "#000000",
    "visualStyles": {
    		"*": {
        		"*": {
            			"*": [{
                			"fontSize": "18"
            			}]
        		}
    		}
	}
}

Thanks,

I noticed imported themes do not affect existing visualisations. If I create new visualisation I see it uses new theme but new theme does not affect previously made visualisations. I tested my code and Greg's one. To reproduce this issue just create any matrix table using any sample of data then implement Greg's theme - in my case theres is no effect. 

I am using Power BI desktop. Should I do refresh or something after implementing a theme?

Hi @Anonymous,

The whole report will apply the new theme immediately when the new theme is imported. Did you use the latest version of Power BI? Please upgrade first.

Yes, I am using the latest desktop version. I think I know where the issue is.

Based on further tests. Left table on the screen below is a newly created one. Right one is previously existing in a report

Let me go through some scenarios:

Scenario 1) - Before applying the theme

Scenario 2) - After applying Greg's theme

Scenario 3) - After applying Greg's theme and Columns Header -> Revert to default

Scenario 4) - After applying Greg's theme, Columns Header  and Row Header -> Revert to default

Scenario 5) - After applying Greg's theme, Columns Header, Row Header and Values -> Revert to default

If I have a visualisation in my report and make formatting changes in sections:

- column header

- row header

- values

And then import a new theme, the theme will not apply in those sections. I have to "revert to default" beforehand.

My conclusion is it seems to be a bug or a significant limitation of Themes. It is hard to trust Themes now, its behaviour is unpredictible.

Hi @Anonymous,

This behaviour is by design. Please refer to desktop-report-themes#situations-when-report-theme-colors-wont-stick-to-your-reports. The customization by users will be respected.
