<Max xsi:type="data:NumberDataElement">
<Value>-5.0</Value>
</Max>

Do someone know how to set y-axis maximum(image1) value become a negative value(image2) ?

In your case, you could just grab the axis label and modify its value to remove the '-' or add the '-', in script. Let me know if you need an example of this.

My mistake. The easiest way I can see, to do this is to create a computed column that multiplies your axis #2 field by -1, plot this field on your second axis and then do what I said above and reverse the positive and negative values in the labels. Let me know you BIRT version if you need an example.

Take a look at this report. I used a scripted dataSet to recreate data similar to yours, so instead of creating a computed column in the dataSet, I made one in the chart by going to the select data tab and selecting the data bindings button and adding a binding. You can see it there. I then used this value for the second series. Finally, I reversed the values, in the second yaxis, in the chart's script. Hope this helps.
