For logarithmic scales it is mathematically IMPOSSIBLE. You can set the min value to 1, 0.1, 0.01, 0.001 etc but NOT to 0! What you can do is to set manual scales, for example: B4X: Copy LineChart1.YScaleLogaritmic = True LineChart1.AutomaticScale = False LineChart1.YMinValue = 0.1 LineChart1.YMaxValue = 500 While testing I found a bug with manual logarithmic scales, the xChart thread has been updated.

Can you perhaps do something like this based on a given filter or criteria: Code: Copy Dim v As Int =Rnd(.1, 10001) 'certain criteria If v < = 100 Then chart.AutomaticScale = True Else chart.YScaleMinValue =1 End If Upvote 0
