Bar Chart Conditional Color Formatting

Hello,

What is the best way to conditionally color bars in bar chart? There is another similar question on this forum (https://answers.flexsim.com/questions/116572/dashboard-conditional-color.html) and the recommended answer was to add "color" as a column in a statistics collector and use that as a variable to control color. However, I am pulling data from a calculated table and couldn't use the if statement in the calculated table, and I also want to do more than 2 colors depending on the value, let's say 0-10 GREEN, 10-20 BLUE, 20 and above RED.

Here's a sample model. I want to change the color of the bars for all 4 zones depending on the average weight value from the "AverageWeight" Calculated table.

BarChartConditionalFormatting.fsm

Software Version:

FlexSim 23.2.0

This is a little roundabout, but it seems to work:

The basic problem you faced is not being able to use if statements in your query. Technically, it is possible to use "CASE WHEN" statements. But in your case, I think that would be a lot of complicated SQL.

The approach I used in this model is a user command. FlexQL (FlexSim's SQL engine) recognizes most FlexScript commands as SQL functions. In this case, I made a function that returns a "rating" word based on a number, in a command called "ratingFromValue" that accepts a single number and returns a string:

double value = param(1);

if (value <= 10) {
  return "Good";
}

if (value <= 20) {
  return "Acceptable";
}

return "Overflow";

You can see that it would be easy to add in more color boundaries in this code.

Then, in the Query Builder, I added a new column:

Then in the chart, I colored by the Rating column:

Hi Jordan,

That worked, thank you!

I was going to go the SQL route and started looking up some SQL code but I thought there must be something simpler.
