C# plotting chart- How to show maximum scale when set fixed interval at same time -

-

i trying plot mschart setting x axis both maximum property , fixed interval. chart plotted not showing maximum scale(tickmark). unless use auto interval instead of fixed interval.

if set x axis maximum value , auto interval, max scale showing.(but interval not want)

chart1.chartareas[0].axisx.maximum = dt.rows[lastpointindex].field<double>("x"); chart1.chartareas[0].axisx.minimum = 0;

enter image description here

if add this, maximum scale not showing.

chart1.chartareas[0].axisx.interval = 0.15;

enter image description here

btw, add points in way:

for (int j = 0; j <= index; j++) { double x = dt.rows[j].field<double>("x"); double y = dt.rows[j].field<double>("y"); colomun1.points.addxy(x, y); }
