- Let’s add a pressure-volume parametric chart to start with
- Drag the Chart from the Blocks palette to the middle column
- Select the middle column
- Set the Height to 50%
- Select the chart
- And name it “Left ventricle PV”
- Select the Line chart - Plot.ly in the Chart type selector
- Open the Dataset pane and click Add dataset
- Each dataset is a separate line in the final chart
- Open the newly created dataset pane
- And name the dataset “PV”
- Disable showing legend, since we only have one dataset
- Bind the y axis to pressureLeftVentricle_mmHg
- Uncheck the x is controlled by time check box
- Bind the x axis to volumeLeftVentricle_ml
- The result should be a plot of pressure vs volume
- A bit too slow
- Click HeartModel in the tree view
- And increase the Step length to 0.008
- Much better
- We need to determine a fixed range for the x axis
- 70 to 160 should suffice for now
- Select the PV chart
- Open the Axes -> X Axis pane
- Click the Advanced button
- Set the “Autorange” to “false”
- Set the “range” to [70, 160]
- Set the Title of the X Axis to “Pressure [mmHg]”
- Let’s move the heart rate to check the y axis range properly
- For the y axis 60 to 160 seems appropriate
- You can always go back and adjust the ranges
- If you misjudged the first time
- Adjust the x axis “range” to [60, 160] and save
- Open the Axes->Y axis pane
- Set the Title to “Volume [ml]”
- And set the “range” to [0, 150]
- Both axes are now appropriately ranged
- In the next part we will add even more charts
