Power of Automation :: Auto-Color Tasks in Gantt chart based on values in Picklist field.

Hello Everyone,

A Custom function is a user-written set of code to achieve a specific requirement. Set the required conditions needed as when to trigger using the Workflow rules (be it Tasks / Project) and associate the custom function to it.

Requirement:-

One of our customers wanted to dynamically update the Task colors in the Gantt chart based on the value selected in the Picklist custom field called Approval Status Picklist. This can be achieved using Task Custom Functions along with Workflow rules in Zoho Projects. 

For instance, when the value "Design" is selected in the picklist, the corresponding task in the Gantt chart should automatically be updated to "Green" color.

Below are the values and color code mapping used in the sample custom function code. However, you can customize these mappings to suit your requirement. 

Values
Task colors
Design
Green
Wait 
Grey
Assembly
Yellow
Test 
Red
Meeting 
Blue

Custom function code:-

if(process.equals("Design")) {
color = "rgb(0, 255, 0)"; //Green
} else if(process.equals("Wait")) {
color = "rgb(124, 124, 124)"; //Grey
} else if(process.equals("Assembly")) {
color = "rgb(255, 255, 0)"; //Yellow
} else if(process.equals("Test")) {
color = "rgb(255, 0, 0)"; //Red
} else if(process.equals("Meeting")) {
color = "rgb(0, 0, 255)"; //Blue
}
changeColor = invokeurl
[
url: endPoint + portalId + "/projects/" + projectId + "/tasks/" + taskId + "/taskcolor/"
type: POST
parameters: {"color":color}
connection: "XXXXX"
];
info changeColor;
return "success";

Ensure to replace XXXXX with the Zoho Projects connection link name, along with the scope ZohoProjects.tasks.UPDATE. Check this link to learn how to create the connection. Please find the screenshot of the parameters to be mapped.
