VBA Conditional Formatting of Charts by Value. Hi Jon, Thanks a lot for you comments. I have tried to do a work around bu can’t manage getting it to work.
Basically what I’m trying to do is to change the colors of each data point in a bar chart depending on its name (XValues). I have in the input sheet the following columns. Name Type. Volvo Car. BMW Car. Boening Airplane. Zodiac Boat. Type definition column: Car. Boat. Airplane. I want the code to do the following (pseudo code): 1) compare each data point in the bar chart with the name column. Once again thans for a great site!/Leo.
Sub Color. By. XValue()Dim r. Name As Range. Dim i. Name As Long. Dim v. Name As Variant. Dim r. Group As Range. Dim v.
Testing Your Procedure. Once you have created a procedure, you need to test it out. VBA provides several different tools you can use to do this. Loops are used for repeating a set of statements multiple times. There are different types of loops in VBA: For Loop, For Each, Do While & Do Until loops.

Error Handling in VBA . By default Excel deals with these, so when a run- time error occurs, you'll see a default error message like this: But you can change this and instruct Excel to allow your code to deal with run- time errors. For the purposes of this article they all mean the same thing .
You can use On Error in four ways. On Error Go. To 0.
On Error Resume Next. On Error Go. To . Resume Next does not fix an error, it just ignores it. This can be good and bad.
The Good? If you know that your code could generate an error, then using Resume Next can prevent an interruption in code execution. For example, we want to create a file, but I want to make sure a file with the same name doesn. To do this, I will attempt to delete the file, and of course if it doesn.
If it does, the file doesn. So before I attempt to delete the file, I instruct VBA to ignore the error. What if the file I am trying to delete is read only? If it is I will get an error when I try to delete it. So an error caused by trying to delete a read only file will get missed. And If I then try to create a new file with the same name, or open it for writing data to it, I will generate more errors and they will be missed too.
You are better off seeing if an error occurred by checking the Err object (see below). Doing this can tell you the error number and help you figure out exactly what happened.
On Error Go. To . This is typically used to specify your own error handling code. None of the code between the line generating the error and the label is executed. Error Handlers. So you write your own error handling code and use On Error Go.
To . So just before the Err. Handler: label, I've used an Exit Sub statement. Multiple Error Handlers. You can have more than one error handler in a routine, but only one of them can be active at any time. You could have something like. Sub Multiple. Error. Handlers(). On Error Go.
To Err. Handler. 1. Err. Number gives you the error number, and Err. Description gives you a description of the error. Resume can only be used in an error handling routine, any other use will generate an error. Resume takes three forms. Resume . If you haven’t fixed the error, your code will begin an infinite loop as it switches between the line of code generating the error and the error handling routine.
If you look at the example sub Resume. I’ve instructed VBA to use my error handler, called Err. Handler. In Err. Handler I’ve attempted to fix the error by assigning num the value 1. If I then used only Resume, all that would happen is that VBA would go back to num = 1 / 0 and another Divide by 0 error would be generated. Instead, I use Resume Next to carry on executing code at the line after the one causing the error. In doing so I have handled the error by assigning the value 1 to num, and execution will continue without another error at the line result = num / 1. Sub Resume. If an error occurs, VBA will use the last On Error statement to determine what happens.
If an On Error statement has been used in a procedure and an error occurs in that procedure, then that error is handled as I've just described. But if an error occurs in a sub that hasn. Sub. Two calls Sub. Three(), and has some code of its own to execute. Sub. Three() carries out a calculation. Here we have our error handler and the code in it is executed.
