Is it possible to plot log curves?

[fliptoback]

Hi there, is there a way we can plot log curves, it would be extremely useful if we can.

Also if there is a way we can manually indicate a point from the x, y co-ordinate? Say I have a graph and i want to manually indicate certain points to see how the curve relates to them.

Is it possible?

Hi, im not sure about the log scales, but you can add point to a graph like this:
so manually adding the x and y values and adding it to the plot by putting & x1|y1 etc.

Thanks Erikbernhart for your reply.

The log-log graph and semi-log graph I refer to are the axis are in "log" scale. Here is a image.

Is there a way we can achieve this?

Recently figured out that we can use Javascript and plot it with the help of plotly library. Thanks to @Proektsoftbg

Hi strsthapa, thanks for that. It is a great solution. On that cloudflare source library, could you elaborate how do i install that library?

[strsthapa]

you don't need to install just use the '<script src="xxxxxxxx"></script> to call JavaScript and plotly as shown above and use div to plot it which will refer script below for the data

#26 -refer this for take function
It works fine,
a = [2; 4; 12]
b = [20; 50; 70]
f(x) = take(x; a)
g(x) = take(x; b)
$Plot{f(x)|g(x) @ x = 1 : len(a)}

I am still getting the error on the backets. do I not just use the "{ [" key on the keyboard to do the bracket?

oh!! your calcpad version is older where matrix was not supported. Download latest one!
