X_Y plot => you set the x, y limits
the QuickPlot => you wheel/mouse/zoom the x, y
Shift wheel mouse for the x
Ctrl wheel mouse for the y
click in plot shift up/dn, left/right to move the plot.

The @ plot is the quick plot. You are correct, it does not autoscale. The X-Y plot that Jean mentioned is a plugin for the PC based software.
I agree, an auto zoom to the correct plot area would be nice

Where is the X_Y plot (axis limits) plugin available for download? Or, if it's already installed, how do you implement it?

I am using windows SMath version 0.99 build 6884.

Thanks!

You must install it using the extension manager (X-Y Plot Region).

OK. I was being stupid...my extension manager was only showing the extensions "local storage". I had to switch it to "online gallery".

Thanks for the reply!

About X_Y plot: so interesting/useful, so bloody freak in other situations.
If the function includes ln(x) and if it starts from very low,
can't start at 0. Start at very low just crashed Smath [yesterday !]

Hello,

yesterday I discovered SMath and I was impressed. I'm Mathcad 15 user, so I like similar behaviour.

But when I started playing with plot I realized that there is no automatic axis setting which is really pain.

I usually use the sheet as "live", so I change some value, do recalculate and instantly see the result in plot. This use is limited here only to small changes which fit in the current plot zoom. If values change more, you can not see them in the plot.

Anyway, thank you for this great tool!

Many users plot functions with an additional plugin named "X-Y Plot" (by user "Uni" )
This plugin offers the possibility to control axis limits (and other stuff) using values or variables coming from previous calculation.
I have moved almost every office calculation tool from plotting with Smath native to "XY Plot" mainly for this feature.

You will find this explained in the XY plugin forum section, or more conveniently in remarkable "interactive handbook" prepared by user MKraska.
Just open the handbook and navigate to Graphics->2D Plot (XY plugin)

Once you will get used with Smath QuickPlot & X_Y Plot,
you will appreciate how superior Smath is vs MCD.
MCD native mesh is ½ pica, Smath is pixel. Thus allows
sizing graphs exactly same width of fine trace vs rough MCD.
1. Size the X_Y plot on your min/max 'x'
2. size Y axis on those min/max ... done.
On rough data points X_Y has spline junction [Isometric example].
For Implicit Trifolium: wait until all frames are calculated,
then see the wind mill rotate ... quick/lovely vs MCD

Thank you both, I need to try it.

I'm now stuck on another thing... I wanted to try to emulate runif and rnorm from MC. And I'm having problems even with runif. See attached.

Thanks,

Your attempted code is illegal, simply.
rnorm is another story ... will be back.

Simply use line() command after function definition as seen on attached image:

Thanks for the "line" hint! Is there any explanation why it is needed?

Attached is something which seems to work, also rnorm included.runif.sm (16 KiB) downloaded 74 time(s).

I used histogram implementation found on this forum. It is little bit slow, but otherwise works nicely.

Is one of very many cases that needs the code be isolated,
particularly this one as it not scalar.
The attached Histogram should work.

Original version does not work SS 6179.
I made simpler otherwise and accelerated timing by ~ 20.
Will be posted soon included in bigger document "Histogram".
