set the Y range

[orensha]

i want the minimum and maximum values to be exactly the start and the begining of the y range.
i need it to fixed every time. how can i do it?

Hi, that's the closest thing i could find at least by the name of the method:
"[_chartView setVisibleYRangeMaximum:_yLength axis:0];"
it doesn't work. is there any way of doing this?

for example CorePlot has this line:

plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(minValue)
length:CPTDecimalFromFloat(_yLength)];

[orensha]

or at least get the area that you set for the graph?

To limit the y range - you can use axisMinValue/axisMaxValue.
If you do not limit it - it will automatically be the min/max values of your y axis.
So I don't see where the problem lies...

i needed to transform the actual value to the container frame point. thats why i needed it to be fixed. but i found that you enabled it with "getPixelForValue". thanks.
