In Tableau, I have a dual-axis bar chart of some data with their margins of error. I am using Gantt bars for the error data, and I want to overlay the error bars on top of the original data. My problem is that I can't figure out how to adjust the placement of the Gantt bars so that they are centered over the top of the original bars, with the error value displayed both above and below the bar.
I am pretty sure I need to create a Calculated Field but am new to Tableau and coding and don't really know how to go about this.
You can do this without the use of Calculated Fields as follows:
Create a Bar Chart with the original data
Duplicate the Bar Chart by Ctrl-Clicking the measure pill in the Rows shelf
You should get 2 charts one above the other now, select one of the charts from the Marks dialog, and change it to Gnatt Bar
Drag error to the Size button of the Gnatt Bar and also to the Color button
Now click the one of the pills in the row shelf and select Dual Axis
Right click the second Axis and select synchronize Axis

I have a graph that shows the ratio (count) of payable vs. processed words among the total words on stacked bars. I would also like to display the same ratio in percentages in lines overlapping the bars.
At the moment I have them in two separate graphs, but I want to merge them so that it takes less space in my dashboard view. I am unable to select the dual combination view as it requires two measures and even though I keep trying to cmd+click+drag the percentage measure pill to my marks, it's only changing the calculations in the bars but not allowing me to select the dual combination view.
Since the percentages are basically the ratio of the green/total in the bars, I don't think I need any complicated configurations for displaying it, however, I am also failing to achieve what I want.
Could you please tell me how to do this visualization?
Edit: I noticed that the reason I couldn't generate the dual combination view was that I had three date pills (year, quarter, month), and by removing two of them, I'm able to generate the dual combination view, but it's far from what I'm looking for as it's only splitting the stacked bar into bar+line.
Neeku, I certainly understand the desire to minimize "real estate" in your dashboard. If I understand your needs correctly, I believe that overlaying a transparent-background chart over the first chart might meet your needs, if a dual-axis chart doesn't work for you (for example, if you wanted to overlay a line chart on a column chart that is itself already dual axis).
By way of example, here is a simple Sample Superstore dashboard with a line chart on top and a stacked column at the bottom.
simple dashboard
Change the line chart to "Floating"
Size it to fit over your column chart and change the background to transparent by clicking anywhere in the line chart and select "Format"
...Format Shading
...and "None" for the color selection
Your line chart is now an overlay, but it's pretty messy.
Click on the line chart and hide field labels,
...turn off "Show Header" for each pill in the line chart
Clean things up and it should look better:
Note: one big issue with this approach is that you will not be able to click to select chart elements of the underlying chart.
I have a data table, group in 2 category A and B as below
data table
How can I create a stacked bar chart like that
chart
There's not a single built in way to make a chart with bars or columns that are able to split like that.
I think the closest you could do would be to make to bar charts back to back. One would filter for Cat A and the other for Cat B.
The legend for each table could be used or a separate legend could be made from a rectangle and some text boxes. The bars' colors would need to be set otherwise it would Automatically use the same initial color for both.
To make the left chart go in the reverse direction, click on the bottom x-Axis and set the Reverse property to True.
Then Hide the Y-Axis of the Chart B.
Is there a way to display color legend on the top left side of a chart .
I have 4 charts in a tableau dashboard and if i display all the legends for all the 4 charts on the bottom it looks busy so I want to include the legends in the charts.
Please help me on this with details steps.
What you want is to make the "legend" a floating object instead of the default tiled object.
To achieve this; You can hold down the Shift key, then drag the legend using the left mouse button while still holding down the Shift key. Drop the legend wherever you wish on the dashboard. Make sure you only release the Shift key after you have dropped the legend at your desired destination.
Warning: Depending on the size of the dashboard you selected, floating objects move around when end users view your dashboard on a device with different screen resolution. To avoid this you can use the "Exactly" size option and define a size range which suits your needs.
To include legends on top left Side of the chart.
Follow steps here as under:
Step1:
Select legends, Right Click on legends top part and select floating and place inside the chart on the top part below heading of Graph as :
So you can follow above steps to add legends in all 4 charts.
Output will look like as
So in this way your legends will not be clumsy and you can describe visualization in a better manner.
I am struggling to create stacked bar chart out of 3 separate bar charts in Tableau.
They suppose to look like this:
However, closest I've got is this in tableau
With other charts it's kinda easier with just dragging the values from rows into the y-axis and voala - stacked bar chart. Over here they just disappear, as I've removed them.
Hope anyone can shed light to my darkness with Tableau.
You were close with your second Tableau screen shot.
From that configuration, move Measure Names from the Columns shelf to the Color shelf. Then you will get a colored bar for each measure on the Measure Values shelf, instead of a column for each measure.
I have created a chart where the x-axis (dimensions) is months, and for the y-axis (expressions) I have a few different data bars, which are compared to the first bar (which is the total).
It is possible to add a slicer or something like that so that I can choose which measurements I want to see? For example, sometimes I need to hide some of them.
In the example bellow: main bar is dark blue one and the other bars for each month is a comparison vs the first one. How can I select for example, to see only the green bars vs the main blue bar and not see all the other bars in that month?
Use filter pane, add filter for each bar, you can select which bar you want to see by these filter.
