Hi I have bar chart with values for two records 5.07 and 0.58 (so they have FLOAT values)
Chart is displayed below:
index.php/fa/11457/0/

You can see that all values are repeated (1,2,3,4,5).
I must mention that there are no too many records in database so maybe in future this will be spread with values on y axis (on example value 100) but how to show now correctly. On example I would still like to step between two numbers not to be smaller than 1, and in future to be automatically be spread. I draw it in Paint like I would like to look now something like this:
index.php/fa/11456/0/

Can you dump the data to a csv file and post it? That way we can help you with a working example.

Hi,

sorry I do not see option to export to csv.
I found where to change this in Format Chart-Y axis and then button scale. Now when I change from AUTO to STEP SIZE (1) I have a nice view.
But my only worry now is when I have for value 100 then it will be hardly readable because it will make 100 lines on Y axis.
So I can not keep it on step size 1 although it suites me very well now (chartresult is now almost liek from the second picture).
When AUTO is ON then when I have value 100 chart will be good.
But now when the value is 5 it repeats me the points on Y axis.
What can be the solution (only solution which I can think of is that I import new report with AUTO option when value becomes 100 and until now to keep STEP SIZE 1 but that is not the solution. I tried with third option STEP NUMBER but that does not show me correctly also.

You could always check the values in a afterDataSetFilled script and then set the step based on that data. Attached is an example that contains two charts. The second chart has a script that reverses the bar scale. This is not what you need but should show you how to set the scale and how to check the data values.
