When using the text command to generate a custom legend, the text is extremely blurry:

Here's the code I used to generate this text:

    text(1362.74, 100, {'{\bf Confidence legend}', ...
        '{\color[rgb]{0.47, 0.67, 0.19} High confidence}', ...
        '{\color[rgb]{0.3, 0.75, 0.93} Medium confidence}', ...
        '{\color[rgb]{0.64, 0.08, 0.18} Low confidence}', ...
        '{\color{black} No confidence (white)}'}, 'EdgeColor', 'k')

Is there a way to make the text clearer? I'm using R2019b, but I've had this problem with R2019a as well.

Double check that you are using a recent graphics card driver.

Hi,

The following could be the possible reasons for blurry text:

Graphics drivers
Screen Resolution

Possible Solutions/Workarounds:

Change the application’s high-DPI scaling mode:

1.1) Right Click on “MATLAB” icon, select “Properties” -> “Compatibility” -> “Change high DPI settings”.

1.2) In the High DPI scaling override area, select Override high DPI scaling behavior, and then try one of the following options:

1.2.1) Application – Disable all Windows scaling settings and only use the app developer's setting. This option was called Disable display scaling on high DPI settings in previous versions of Windows.

1.2.2) System – Overrides the program’s DPI settings and makes it run like it would on a low-DPI display. On a high-DPI display, this will make the program appear blurry.

1.2.3) System (Enhanced) – Windows will try to use enhanced DPI scaling for this program. As a result, some programs will display with crisp text on high-DPI displays. This won't work for all programs.

2. Alternatively, you can also fix scaling for apps in Settings and scale the size between 100% - 500%.
