I'm currently trying to figure out a way to change the measurement values of a AutoCAD drawing (plot/printed). I have 1 drawing with multiple parts, but the only thing that needs to be changed (almost weekly) and that is the values of some measurements for these parts.
I've looked to Excel for a way to make a sheet where i can fill in these values and they get changed instantly. It can be an .PDF file that gets changed, the drawing needs to be printed anyway so no direct insert into AutoCAD needed.
Any tips or advice is welcome!
Cheers,

I'd like to automate the creation of monthly reports. I have a database through which I can export an Excel file (or csv, for the record). The table format is such that the number of columns (~500) will always be the exact same, but the number of rows (25-100) is variable.
The end goal is an excel tab with a few graphs/charts based on said data. For the charts, I'll only need to use maybe 10 columns of data out of the 500, but all of the rows.
I would like to automate the creation of this report as much as possible. Ideally, it will be able to be used by people with limited Excel knowledge. I would think I could set it up such that they can export the file out of the database, input it into my created sheet, and receive an output of charts.
This seems simple but I can't find much info on something like this. I just want to tell Excel "for every inputted file, make a pie chart out of these columns, a line graph out of these columns, a bar graph out of these...etc etc"
Power Query is where I started, and it helped to clean up the large number of unneeded columns, but I don't see where the functionality to automatically create charts comes into play. Macros/VBA seemed like an obvious next step, but I'm worried about how to set it up such that other users won't have to mess with the macros to get a desired end result. Again, ideally it would be as simple as inputted a file path, clicking a button, and getting graphs outputted.
Any tips or advice on how to approach this or what Excel tools that would be easiest to use would be great. Thank you in advance!
I have a existing chart in pptx file, i just want to update its values on daily basis, these charts are already plotted from excel and paste into pptx, i just want to modify the charts ,
but i don't know how many properties are there in charts like series, category and title properties.
i am able to print the chart series and category data, but when i modify these with chart.replace_data(chart_data)
i am getting error like below
return self._chart_part.related_parts[xlsx_part_rId]
KeyError: 'rId4'
I ma using below code to print the values ,
for series in chart.plots:
for i in series.categories:
cat_list.append(i)
for series in chart.series:
for value in series.values:
ser_list.append(value)
the graph looks like below
How can i modify such graphs with updated values which i will be passing from excel to pptx.
I suspect the problem is rooted in the "pasting from Excel" step.
One thing you can try is to right-click on the chart and choose "Edit values in Excel". If that doesn't work for any reason, that would explain the error you're seeing. If it does work, try saving and run the python-pptx code against the saved version.
An alternative, perhaps more reliable fix would be to recreate the chart natively in PowerPoint, starting from adding a new column-chart and adjusting it until you get what you see here. Then you should be able to update it daily with pretty much the code you mentioned (although your ser_list variable will accumulate values for all series in the chart if there is more than one).
To understand why this could be happening, it's important to observe that a chart does not have to have an Excel worksheet "behind" it. It can, and perhaps does in this pasting case, simply have fixed literal values that are embedded in the chart XML itself. The up-side of this is the pasting operation doesn't need to create a whole Excel spreadsheet, which might be tricky in a cut-and-paste context. The down-side is the values can't be conveniently changed using the standard methods.
I haven't tried working with one of those lately so I don't know if editing and saving the data adds a new Excel object created from the embedded values or not, but this might explain the behavior you're seeing.
for the longest of times I've been trying to achieve this to no avail. It seems like it should be a common problem but still I haven't been able find an answer. What I want to do is:
Have a chart in Excel and/or Powerpoint.
Copy this chart as a chart object into PPT.
Keep all characteristics of the original chart but maintain it editable (i.e. - add/remove axes, data labels etc)
Break the link to the original chart/workbook but keep the data editable. I.e., I want a new excel sheet opened when I want to edit the data, just like it works if I create a new chart object.
Preferably, I would like to convert the data of the original to this new chart sheet but this is not of really high importance.
Basically, I want to be able to use graphs as templates for a new graph without editing the original data. Please help!
PS. I didn't include any code as most of the code I've tried has tried to achieve something else. I mostly want to know if this is even possible to do (it should be!)?
I couldn't find documentation to help me with this problem - [EDIT: ...and the only recommendations I've gotten from colleagues is what I have mentioned below].
I'm developing 23 figures that must include a PNG image of a state, and two charts with accompanying state data. Each chart has a slightly different scale, though the units will be the same (I say this because it makes formatting a headache). The only way I know how to make these figures is to create a slide in Powerpoint, inserting the charts and PNG and formatting each slide "by hand" to match all the others. This is time consuming and aggravating, and I'm optimistic there's a better way.
Question: What program/methods do you recommend for creating a standard figure format?
Ideally I would like to copy-and-paste charts from Excel, and insert a PNG image.
You could look into R to do this. Not sure what the PNG image is, but you can use R also to plot data on maps (using heatmaps or otherwise) if you would want to. You can import an image so you can also work with your PNG image if needed.
As for the charts you then could create them using R instead of excel and put everything together.
This way you can write a piece of code once and generate all the figures you need.
I need to feed data into a line chart with VBA. I need to give a basic unidimensional range when I do it with Excel in a raw test. The thing is that now I need to hide some things in VBA code, so that the user just sees a curve resulting of some basic input at the click of a button.
I think there are at least two options for me :
either have the chart object placed in the Excel before, and having it point to some VBA snippet. In this case, should I somehow point to VBA from Excel ? Or would VBA access the chart area by some ID ?
create everything dynamically from VBA, the chart window, the chart, and the series input. This might be trickier to figure out maybe as I have frozen panes, so there would be the question of which pane is active (I'd like to avoid to have to do Selects to select the right one)
What would you recommend ? And in either case, how to actually do it ? What type of data to put in ?
Thank you so much !
I was involved in a project a couple of years ago that might be relevant.
A report was created monthly for the organisation's management board which contained dozens of charts. It was a near full time job for a statistician to collate and process data from across the organisation that provided the source data for these charts. I was asked to automate what could be automated.
It became clear that the appearance of the chart could not be automated. The statistician and the management board's staff held regular discussions and often agreed minor changes which they thought would better present the organisation's performance.
I could automate the collection of the data, its processing and placing of the results in the ranges from which the charts got their data. The most I ever did with a chart was change the size of a source range.
What would be the parameters that would control your macro's changes to a chart? How would your macro get the determine: type of chart, nature of the axes, text, etc?
Hope these thoughts help. I could look out my notes if my experience seems particularly relevant.
