Creating 2-dimensional plot in DWSIM

[The One]

How can i create a 2-dimensional plot in DWSIM given 2 arrays of same size?

[Daniel Medeiros]

On Python?

Hello,
I also tried several ways to chart data with a DWSIM script.
But for what I found, matplotlib can't be used, and ironplot library doesn't work (it gives an error that I don't know how to solve).

Eventually I found and adapted a very basic procedure that produces 2D plots with MSChart.
In the attached DWSIM simulation you will find a script that allows to obtain graphs once the data series are populated in the relevant part of the script.

It could be nice to have a charting plugin in the next DWSIM releases.
Hope this helps you.

Thanks a lot Luca Finardi

Guys, check the dynamic simulation tutorial, there are a lot of 2d charting examples on it.

Thanks Daniel for addressing to OxyPlot included in the Dynamic tutorial.

However I could not make it it working. I tried this simple:

import sys
sys.path.append(r"./Lib")
import site
import os

import clr
clr.AddReference("Eto.OxyPlot")
clr.AddReference("OxyPlot")

import OxyPlot
from Eto.OxyPlot import Plot

from math import *
x = [i * 0.1 for i in range(100)]

chart1 = Plot()
chart1.Model = Common.CreatePlotModel(x, [sin(xi) for xi in x], "Plot1", "", "x", "Sin(x)")
chart1.Model.InvalidatePlot(True)

form1 = Common.GetDefaultEditorForm("Test", 600, 600, chart1, False)
form1.Show()

but I got the error:
Error running script: Traceback (most recent call last):
File "<string>", line 16, in <module>
ValueError: Specified argument was out of the range of valid values.
Parameter name: Type for 'Eto.OxyPlot.Plot' could not be found in this platform </module></string>

Any suggestion? (I am using DW 5.7u14)
Thanks

Sorry guys, the code in the dynamic tutorial only works on the Cross-Platform UI. For the Classic UI (Windows Forms), try the following:

import sys
sys.path.append(r"./Lib") 
import site
import os

import clr

clr.AddReference("OxyPlot")
clr.AddReference("OxyPlot.WindowsForms")
clr.AddReference("System.Windows.Forms")
clr.AddReference("DWSIM.ExtensionMethods.Eto")

import OxyPlot

from OxyPlot.WindowsForms import PlotView
from System.Windows.Forms import *
from DWSIM.UI.Shared import *
from System import Array

from math import * 
x = [i * 0.1 for i in range(100)]

# generate and display a nice chart

# create a new Plot model

# http://dwsim.inforside.com.br/api_help5/html/T_DWSIM_ExtensionMethods_OxyPlot.htm

chart1 = PlotView()
chart1.Model = Common.CreatePlotModel(Array[float](x), Array[float]([sin(xi) for xi in x]), "Test", "", "x", "y") 

# update the chart data view

chart1.Model.InvalidatePlot(True)

# setup and display the chart

form1 = Form()

chart1.Dock = DockStyle.Fill

form1.Controls.Add(chart1)
form1.Invalidate()
form1.Show()

Thanks Daniel for this clarification.
I tried your example with the classic UI, but to me it only shows an empty form (see attachment).

[Daniel Medeiros]

Try resizing the form. The Invalidate() call is responsible for updating the form contents. I've tested it here and it worked as expected.

[Luca Finardi]

Here instead the form does not resize and after a while disappears.
