 Scale range for Y-Axis |

Hi Peter
I am plotting a linear graph where the scale of the y-axis id user defined. However, for some
values defined I get the actual scale plotted to be slightly higher. This happens only for
certain values.
Example: See attached image of the graph
Y-Axis Scale is -0.15 to 0.14
Plotted scale: -0.2 to 0.2
The command I used in VB.NET is c.yAxis.setLinearScale(-0.15, 0.14). Based on the other
postings, i tried using c.yAxis.setAutoScale(0, 0, 0) after calling setLinearScale but it made
no difference.
I need the graph to be plotted in the scale specified in the y-Axis. Your help is very much
appreciated. Thanking you

Hi Ariffin,
By default, if you do not fully specify the axis scaling configuration (which includes the axis range as well as the tick spacing), ChartDirector may adjust the axis range so that it starts and ends at a tick position.
For your case, there are two methods:
(a) Add a line "c.yAxis().setRoundIng(False, False)". This will disable ChartDirector to adjust the axis range to start and end at tick positions.
or
(b) Use "c.yAxis().setLinearScale(-0.15, 0.14, 0.05)". As the tick position is specified, ChartDirector will not adjust the axis range.
Hope this can help.
Regards
