I have recently upgraded from Office 2010 to 365. I imported a CSV data file into excel to create a plot from the data. The data appears correctly, but when I insert a chart to plot the imported data, all values appear to be zero. It seems that in some instances the data is displayed in the cell, but cannot be plotted.
My initial reaction was that the format of the imported data may have spaces or other characters forcing the cells to contain text rather than numbers, but this isn't the case (see below for a sample). Changing the cell format after import does nothing.
I can perform operations on the problem data using a formula within excel (e.g. '=A1 + B1') and everything works. If you add two of the problem cells together, you get the correct result in the correct format and the new cell contains a value that can be plotted.
If I import the same delimited data file into Excel 2010, then everything works fine, including plots.
What has changed between the two versions that could cause this unusual behaviour?
See below in the screenshot, I have plotted a series of decimal values in Excel (O360) after transposing the original data, and the plot shows all zeroes on the y axis despite the cells containing data. It does not see them as values for plotting, but it does see them as values within formulae - which is very odd.
Note: In the plot below I manually typed the left most column which forms the x axis
This is the format of my imported data row. I see nothing wrong with it:
0.312551;0.137288;0.137288;0.283603;0.200974;0.223328;0.200974;0.223328;0.194638;0.240637;0.194637;0.240637;0.0930865;0.0930865;0.047336;0.047336;0.0646357;0.0646357;

Is there any way to exclude values from a chart that are '0'? The data source is a mixture of vlookup's or sums where the results have a value others are '0'. When I plot the chart and there are some axis points with all '0' - can these be excluded to only show columns with data present?
Changing the source data to blank cells stills plots the data. There is an option on the line charts to join/connect empty cells but there is no function that I am aware of for a column chart.
Indeed it is:
Change your formula(s) to an if statement, so that it return NA() instead of 0. The chart won't show/include N/A values, however the label will be viable still as a standard. You may hide this label.
This method will work in this case if I understood your OP correctly. However, it may not work in all cases, as hiding 0-values from graphs may or may not require a different approach.
In Excel, I have a column chart with data labels. The source data consists of formulas which occasionally result in #N/A values. Currently, the data labels for #N/A points are literally displayed as "#N/A". Is there any way I can have Excel suppress the data label altogether if the underlying value is #N/A? If I use =IFERROR(A1,""), then that displays a 0 so that does not work.
You could set the number format of the labels to not display anything when it interprets a zero, if you don't want to display anything even when the formulas evaluate to zero.
There is a very in depth discussion of techniques such as this here:
http://www.mrexcel.com/forum/excel-questions/568361-charts-data-labels-using-%3Dna.html
I had this problem as well and found the easiest solution is to
duplicate the chart data fields
add those as new series to the chart data
change the series chart type for the new fields to a line chart with no line and no marker
show the data labels only for those new fields.
(column charts will show #N/A, line charts do not).
I have several data in excel sheet and I wonder if its possible (through macros or something else) to select the data and display the series needed.
I'm not quite sure if I explained the situation correctly...
But I have multiple curves, and instead of plot the average curve or single curves, I would like to have the option to plot: curve 1, curve 2, curve 3, average curve...
Kind regards,

My preferred way to do this is with a combination of a couple of ideas. In general, Excel charts are easiest to maintain if they are looking at a simple range instead of complicated named ranges. Given this, I like to create a simple column of data for the chart and then use other Excel features to modify that column of data.
Note that the steps below are for a specific case of a block of data all on one sheet. There are a ton of variations that you can do to make this work for other configurations. The idea is simple: create a new column of data for the chart and use normal formulas to get the data there. You can make the x-axis a selector as well.
For the simple case of a common x-axis with varying series for the y-axis all in one block of data, I do these steps:
Start = block of data
Add a column header off to the side which will "drive" the selection. I like to make this a Data Validation drop down so that the selection is correct. I did this in G2, selecting the column headers as the Source.
With this in place, you can use the selection there to update the data in the column below it. A simple formula for doing this uses INDEX.
Formula in G3, copied down to end of data: =INDEX($C$3:$E$25,,MATCH($G$2,$C$2:$E$2,0))
This formula works by finding the column name in the list of column headers and returning that column of data. Since the row selection is blank ,,, it relies on the relative position of the cell which works since everything is lined up.
Once this is done, you can then create the chart simply using the date and the new column of data. It will respond to changes in the selector which works nicely. If you use the column G header as the series name, that will update too which is a good effect for free. Below is the chart showing the ranges it is using.
I am interested in plotting an excel graph exactly like in the image I am pasting here.
It has been obtained from tables arranged like this
The table has been arranged in excel.. However try as I may I am not able to put my data (arranged in the same manner in excel) into a similar graph/chart. Has anybody previously worked with a chart template like this? If so, please direct me to it. When i put 2 values in a single cell with the colon separating them, the charts I plot are not even eble to recognize the number before the colon as a single value and the number after the colon as a single value. Please help.
Excel charts plot sets of single numbers. 123;456 is not a single number.
What do the members of each pair signify?
Here's one way to approach your problem:
Keep the range containing the ;-separated values. This range will be for display.
Create another range that has two columns for every :-separated value, and split these into separate values. This range will be data for the chart.
Note that you'll need both X and Y values for the points you plot, and plotting a vertical line for each point requires a little finagling.
I am trying to draw a line graph in Excel 2010. The y column data source has some gaps in it and I want these to be ignored for the graph. Seems to default these to zero. I know the "Hidden and Empty Cell Settings" exists, but this is only giving the option to set it to zero. Any other way to get my graph looking the way I want it

if the data is the result of a formula, then it will never be empty (even if you set it to ""), as having a formula is not the same as an empty cell
There are 2 methods, depending on how static the data is.
The easiest fix is to clear the cells that return empty strings, but that means you will have to fix things if data changes
the other fix involves a little editing of the formula, so instead of setting it equal to "", you set it equal to NA().
For example, if you have =IF(A1=0,"",B1/A1), you would change that to =IF(A1=0,NA(),B1/A1).
This will create the gaps you desire, and will also reflect updates to the data so you don't have to keep fixing it every time
In Excel 2007 you have the option to show empty cells as gaps, zero or connect data points with a line (I assume it's similar for Excel 2010):
If none of these are optimal and you have a "chunk" of data points (or even single ones) missing, you can group-and-hide them, which will remove them from the chart.
Before hiding:
After hiding:
In the value or values you want to separate, enter the =NA() formula. This will appear that the value is skipped but the preceding and following data points will be joined by the series line.
Enter the data you want to skip in the same location as the original (row or column) but add it as a new series. Add the new series to your chart.
Format the new data point to match the original series format (color, shape, etc.). It will appear as though the data point was just skipped in the original series but will still show on your chart if you want to label it or add a callout.
There are many cases in which gaps are desired in a chart.
I am currently trying to make a plot of flow rate in a heating system vs. the time of day. I have data for two months. I want to plot only vs. the time of day from 00:00 to 23:59, which causes lines to be drawn between 23:59 and 00:01 of the next day which extend across the chart and disturb the otherwise regular daily variation.
Using the NA() formula (in German NV()) causes Excel to ignore the cells, but instead the previous and following points are simply connected, which has the same problem with lines across the chart.
The only solution I have been able to find is to delete the formulas from the cells which should create the gaps.
Using an IF formula with "" as its value for the gaps makes Excel interpret the X-values as string labels (shudder) for the chart instead of numbers (and makes me swear about the people who wrote that requirement).
Not for blanks in the middle of a range, but this works for a complex chart from a start date until infinity (ie no need to adjust the chart's data source each time informatiom is added), without showing any lines for dates that have not yet been entered. As you add dates and data to the spreadsheet, the chart expands. Without it, the chart has a brain hemorrhage.
So, to count a complex range of conditions over an extended period of time but only if the date of the events is not blank :
=IF($B6<>"",(COUNTIF($O6:$O6,Q$5)),"") returns “#N/A” if there is no date in column B.
In other words, "count apples or oranges or whatever in column O (as determined by what is in Q5) but only if column B (the dates) is not blank". By returning “#N/A”, the chart will skip the "blank" rows (blank as in a zero value or rather "#N/A").
From that table of returned values you can make a chart from a date in the past to infinity
