Plotting #67

Closed Saman-Khan closed 1 year ago

Saman-Khan commented 1 year ago

Hi, while vp command can be used to plot 1D variables, data on your axis and time on x axis. How can we plot 2D data. Variable A on x axis and variable B on y axis. Any help would be appreciated

You cannot out of the box. You have to program this yourself.

In most cases, drawing on a field view or image view is the real solution.

Thanks @ahasselbring that seems a good idea. If u can just highlight the code to be looked for adding code to plot as 2D. As u have extensive knowledge of code , a proper direction from u saves a lot of time. U once suggested how to add force to objects on simulator and the help worked really well. So, if u have any hints on where to look for, it will be great. Also, I understand that u must be busy, so it's fine if u don't discuss. Also, it's a request to please keep issue open for a few days so that someone else can reply. @ahasselbring I am really glad that u gave me right direction of plotting in field view. I will always be indebted for your time and support 😇

Also, the image using update method returns only current position of object. Let's say, the ball, but the need is to retain all previous values, previous positions on field view , any hints on doing that @ahasselbring . Apologies in advance to disturb u

You can keep a buffer of the previous objects and draw them in a loop with the same drawing ID (if I am understanding correctly what you want to do).

Thanks @ahasselbring the buffer idea worked well. I was wondering how the cards for opponents are set. I am talking about Code Release 2021. I want to know, is there a way, in which, i can assign a specific card to , lets say player 9, of opponent team. I badly need some words of wisdom on this. This will be my last question i promise. I hope u reply
