Is there a way to pad the min/max value of the y axis scale in Line Chart? So if the minimum plotted value is zero (0), I'd like to see -1 on the chart even though no data is plotted to that value. This just adds a little space to the top/bottom of the plotted data. Similar to what jpgraph offers as described below:
JPGraph option:
Use the SetGrace() to specify some extra space (as percentage of the scale) between the min/max value and the limits of the scale. For example $graph->yscale->SetGrace(10) gives 10% extra space at the ends.
Thank you.
