Option "Showing Values" don't show values

When I create a graph and I want to show all values, values too closed to each other can’t be shown because some values are too big

Hello @David_Bigan,

Please try resizing the chart in height (either drag the chart by the blue handle on the bottom edge or in the right-side settings panel enter the dimension manually in the input field Height (px).)
Also, you can reduce the font size of the values in the settings panel on the right. Select Fonts / Advanced settings.
If none of that help, you can add the missing value manually as a text block. Here’s also a tutorial on Adding text.
