Custom nTicks for each variable in PCP

[Atulsingh92]

Hello,

I have a following definition of a PCP chart, where all the variables are integer variables,

plot3 = PCP(show_bounds=False, 
            n_ticks=5,
            labels=["ntr","nr","np", "nf", "fincon", "tcon"],
           legend=(True, {'loc': "best"}),
           tight_layout=True,
           figsize=(12,8), fontsize=16) #.add(entry.pop.get("X")).do()
plot3.add(dspace, color="grey", alpha=0.3)
plot3.add(res.X, color="blue", linewidth=3,label="min {}".format(obj_names[0]))#plot3.add(res.X[Imax], color="orange", linewidth=3,label="max {}".format(obj_names[0]))#, obj_names[1]))
plot3.show()

Although the 5 ticks work fine if the bound is large, my last two variables are sampled between only 2 and 3 values, so they don't need 5 ticks.

The question is, how can I customise ticks for each variable, if that is even possible?
(np would need 4, fin con would need 2, and tcon would need 3, rest are fine with 5)

Yes, you can do that but you will have to write your own PCP class at this time.
So far the PCP code is not too long, so I recommended copying the class and to change this part

            if self.n_ticks is not None:
                n_length = 0.03
                for y in np.linspace(0, 1, self.n_ticks):
                    self.ax.hlines(y, i - n_length, i + n_length, **self.axis_style)

In your case, n_ticks could be a list and with self.n_ticks[i] you could customize the number.
