VBA Word change graph data point width


If you have been playing with the chart in Word or Excel you might encountered that the point on the graph is quite small.

If you need to adjust the data point on Word graph, you have two options do it manually or simply automate it at runtime using a VBA code.

Assuming you have all the necessary parameters that creates the graph via VBA, and you just need to adjust the data point you can use the code below, the code below was tested using Word 2016. It may not apply to older versions but I think logic should stay the same.

cht.SeriesCollection(1).Format.Line.Weight = 9.75

To do it manually, click on the data point and right click on it and select “Format Data Point”, click the bucket icon and change the width value.


Here’s the screen shot using Word 2016:


For the sake of completeness, the code will be something like this:

Dim shp As Shape
Dim cht As Chart  

Set shp = ActiveDocument.Shapes.AddChart(xlXYScatterLines)  
  
Set cht = shp.Chart

Dim wb As Excel.Workbook
Dim ws As Excel.Worksheet

cht.SeriesCollection(1).Format.Line.Weight = 9.75  'change the width value to a desired one

Output will be something like this, the data point is quite big.

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')

WMIC get computer name

WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
Why would you need a command line tool if there’s a GUI to check?
If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username.
If you have remote computers, you need to delegate someone in the remote office or location to check.
Or you can just write a batch file or script to automate the task.
Here’s the code below on how get computer model, manufacturer and the username.
Open an elevated command prompt and type:
wmic computersystem get "Model","Manufacturer", "Name", "UserName"
