Why Excel graphs are adding empty data points? - excel

I want to plot the sales on specific dates. But of course there hasn't been sales on some weekends and holidays, so i dont want to plot these days. Just skip these days in the graph. But as soon as i create a bar chart in excel and select the data points, excel automatically put the other dates in without data. How can i force excel to show only the data points i provide?
I attached to data point and the graph which excel creates.

In the colum (or row) of data representing your dates, ensure they are string literals and not date values. You can do this by prepending a single-quote, e.g.:
'14/04/2017
Strictly speaking, you only need to do this to the first date.

easiest way is to format the x axis with the following option: Axis Type: Text Axis

How to color data series point inside plot graph depending on data value in Excel table

On a data/line plot inside Excel, I'd like to color my data points depending on a value inside the table on the same row as the data value, however from a different column.
It's best explained with a picture:
It's essentially a line chart type with the lines removed, and the data points set to bullet type and given an increased radius for visibility. The x-axis denotes the calendar date as dd.mm, and the y-axis contains the values.
Now the Excel table also contains a row called "Time of Day", which can be mo(rning), mi(dday), ev(ening).
Can something like this be done with a line chart, or do I need to use a different type of chart, or is this generally not possible in Excel (which I doubt)?
Excel in use is: Microsoft Excel for Mac, Version 16.51 (21071101).
Here's a way to achieve this:
What I've done is:
Added three columns for the times of day (columns B, C and D). These can be hidden.
Added this formula in B2: =IF($E2=B$1,$F2,NA()) which should then be dragged to cover the next two columns and then down to cover every day.
Selected A1:D11 (it'll be more than 11 on your version)
Went to Insert > Chart > Insert Line or Area Chart > Line With Markers
At this point you have a line chart with three series (mo, mi, ev). The lines can be removed, which just leaves the markers. You can format each series separately, with different colours, shapes, sizes, etc.
As a special bonus, this automatically gives you a legend that explains the colours.

Plotting processing time

Below is the average time taken for a robot to process a single request on any given day. I am trying to plot this on an excel chart but I am having trouble formatting. I want the date on the x axis and the processing time on the y axis. Any advice would be appreciated.

Create a line chart. With the data in two columns, make sure there is a header row. Delete any content in the date header, so the cell is blank. If there is text in the column header, Excel will try to plot the dates as numbers, and that is not what you want.
Click any cell in the table and insert a line chart. By default, if Excel recognizes a date for the X axis values, it will plot the data on a timeline. In the screenshot, notice that there is a gap of a few days and the chart plots the data correctly per day.

Excel: How to weeknumbers in number formatting

I would like to use weeknumbers in number formatting in Excel, in particular in XY-graphs.
The built-in function WEEKNUM() can be used to extract the weeknumber from a date. With these weeknumbers I can proceed in two different manners:
use the weeknumbers as text labels on my graph axis. This does not give the required result as labels are distributed evenly on the axis. A sequence like "13" "14" "33" would put the label "14" just in the middle.
use the weeknumbers as numbers on my graphs axis. This would resolve the above problem, but gives a gap at years end. E.g. 1652 (week 52 in 2016) and 1701 are 49 units away from each other.
To illustrate, please see these two graphs. The graphs indicate a tracking of a project plan, i.e. planned versus actuals. The first chart is a correct graph somewhere in the midst of a year; the second chart is more or less the same graph crossing year's end.
Correct chart, in the midst of a year
Chart showing problem at year's end
Now I'm stuck. My preferred route would be to add a number format to the generic number formatting methods in Excel. E.g. similar to be able to use yyyy for years and ddd for days, I'd like to use ww for weeknumbers.
How can I achieve this?
Not certain I'm understanding the question fully, but if you're wanting to ensure the end result is treated as a number you could use =Text(WEEKNUM(A1), "#") which would convert it to a numeric value.
For the chart, sounds like you could use the axis options (right click on the axis labels >> Format Axis). There are multiple options that would allow you to change how the labels are displayed.

Excel 2013 Why is standard deviation not evenly stretched to both sided up and down?

I calculated data in Matlab.
Now I want to format it in excel.
The values in first row represents some average values. The values in second row represents standard deviation.
I try to draw a graph, but standard deviation bars do not strech up and down evenly, as they should.
I want to achieve graph like this:

It is VERY important you delete all the data, when you set custom values from both textboxes (after you click specify values).

Excel - Custom label format to turn "1999Q4" into "1999"

I have a column of data in the form 1999Q1, 1999Q2, 1999Q3, 1999Q4, 2000Q1, etc. I would like to show these in a graph simply as 1999 and 2000—essentially, to just use the first four characters of the cell data.
In the Format Axis dialog under Custom label, I've tried using #### and 0000, but neither format seems to have any effect on the display.
What would my custom format have to be to make 1999Q2 display as 1999, and so on?
I could be wrong, but I don't think you can do that with custom formats.
What kind of a chart are you using? If it has a categorical x-axis (line, column, bar), then I would create another column. In that column use a formula, such as:
=Left(A1,4)
to get just the year numbers. Then use that column for your X-axis Labels.
An alternative would be to split the year/quarter into two columns like this:
Notice the x-axis layout that you get when you select A1:C9 to create the chart.
