Hi everyone!
I am trying to set up a blood pressure chart in KNIME. The data is very simple: there are three columns (systolic, diastolic, pulse), and the rows are identified by the date the measurement was taken on. I would like to make a plot (e.g. line plot or bar chart) that would indicate the level of each measurement, such as green for normal, orange for elevated, red for high. However, each column has a different value for this, e.g. systolic is normal below 120 and diastolic is normal below 80. How can I obtain this? Or alternatively, is there a way to color the background or annotate the axis with this information?
@marieclaire you can take a look at this variation with KNIME Data Apps and Python graphics (using just the bundled Python version so no big installation necessary). You can add 3 columns to the chart and enter 3 thresholds for each value along with some labels.
The elements of the chart can be configured in the dialogue of the component so the framework can also be used for values other than blood pressure and pulse and no need to go deep into the code itself.
The date axis can be configured like in this example - you can let the system make the decision which scale to use and you can rotate the labels on the x axis.
