1.85 exponential axis plot - possible?
显示 更早的评论
I m new to Matlab, I just wanted to know whether is possible to have the X axis values (ticks) of a plot raised to the power of 1/1.85. Intent is to plot the following equation
P = a * (Q/C)^1.85 * (L/D^4.87)
where a, C, L, D are known constants. The plot needs to be drawn as a line, so basically I need to plot the P(Q^1.85). That's easy enough, however the problem is it seems I cannot have the x axis showing the Q values, not the Q^1.85. That's very similar to a semi-log plot, only that it is not realy a log plot rather a semi-exponential plot of 1.85.
Is it possible? Any suggestions?

You can set your tick labels to be whatever your want. The label and value are indpendent properties. One approach would be to determine what Q values you want to have your ticks at, place the ticks using the value Q^1.85, but then set the labels to the Q value.
Q=100:10:1000;
plot(Q.^1.85,P)
tickLoc = linspace(0,ceil(Q(end)),9);
set(gca,'XTick',tickLoc.^1.85,...
'XTickLabel',string(tickLoc))
