Plotly gauge chart r

In my current project I had to create a gauge chart with plotly. There is an example on the plotly website for Python, Javascript and R. If you take just a quick look on this example, you might think it is quite easy to implement and use it. But if you take a closer look how they did the gauge chart you will facepalm yourself.

So lets take a closer look on this example. You may wonder why half of the image is white and if it is an error. But as you will see later, this is caused by the chart they build. The trick they did is to put a hole into the pie with an radius of 0. N is the number of gauge chart elements you want to have.

So as I just needed 4 gauge chart elements, i had to write 5 elements into value array:. I also removed the labels section and modified the colors and text sections to fit my requirements. I modified the last color that you can see how the chart is drawn.

The problem you now have is to remove the half of the bottom block you got. For that you have to do some css magic. Realy important is to choose the same height as width! Otherwise the calculated pointer will not point on the correct value, because the x and y position of the pointers end is calculated by using Math.

I will pick up this point later, but for now we will focus on removing the bottom part:. First we want to hide the lower part of the chart, for that we have to restrict the height of the outer container to the half of the chart size. I choose to take 20 px more because it gives a nice effect if you have a small grey bar on outer edges of the gauge chart elements. The red dot of the pointer also needs to get into our visibile chart, there are 2 options:. I would prefer to choose the first version.

So this is how the final result should look like.

The pointer is represented by an svg-path and small scatter in the middle of the chart. The svg-path is the reason of the problem, the total path is set up by 2 constant points and one calculated point for the top of the pointer. You can see the 3 points in the following image, the A marks the first point of the svg-path M.

If you come to the point that your C is on top of the other 2 points the triangle wont be drawn. There is a small workaround to fix this, if you just switch the A and B points from top and bottom to left and right ordered. To fix this, we will put an if statement onto the svg-path structure:.

You will recoginze small thickness changes when you get your curser near the boundary. To get a correct triangle you have to move your A and B points with your C point.

You have seen that it is possible to create Gauge charts with plotly. But it is not as simple as it looks like on the first glance. It is kind of tricky and a bit hacky.The Plotly-Shiny client has been updated with the 2. Read the new Plotly-Shiny client tutorial. Using Shiny and Plotly together, you can deploy an interactive dashboard.

That means your team can create graphs in Shiny, then export and share them. Shiny apps involve two main components: a ui user interface script and a server script. The user interface script controls the layout of the app and the server script controls what the app does. In other words, the ui script creates what the user sees and controls and the server script completes calculations and creates the plots.

To make a shiny app that is a plotly widget, just add 3 scripts to your app folder in addition to the ui. R and server.

Steps typically are broken into several values, which are defined with an array. The bar represent the actual value that a particular variable reached, and the threshold usually indicate a goal point relative to the value achieved by the bar. See indicator page for more detail. Below is the same example using "steps" attribute, which is shown as shading, and "threshold" to determine boundaries that visually alert you if the value cross a defined threshold.

The following example shows how to customize your charts. For more information about all possible options check our reference page.

Then now you should see that a new custom visual is installing and a new package has been created, but what is inside the packages. Length and the Species there. But as you can see in the picture above, you will get an error that you need to provide the name, description and so forth….

Hi Lelia, Great walkthrough as usual! I tested the script. If you may, we can exchange the. Hi Ivan, Sorry I got busy yesterday a bit, it seems you find solution Thanks for following my work. At the Power BI end, I believe the values are hard coded in. So if you wanted to switch from Value on the x axis, you would have to change the r script in the pbiviz folder.

Rather than drag and drop in Power BI. Hi John, I should admit now I able to do that separate x,y, the legend by changing the capabilities. Indeed this is exciting. Hi Leila, Can you please share the toy script you demonstrated in this blog. Thanks in advance Lalit Chaudhari. Hi Lalit, there is a technical problem for sharing files, I will put in GitHub soon and will announce in blog.

The bar shows the target value, and the shading represents the progress toward that goal. Gauge charts, known as speedometer charts as well. This chart type is usually used to illustrate key business indicators.

The example below displays a basic gauge chart with default attributes. For more information about different added attributes check indicator tutorial. The following examples include "steps" attribute shown as shading inside the radial arc, "delta" which is the difference of the value and goal reference - valueand "threshold" to determine boundaries that visually alert you if the value cross a defined threshold.

Basic Gauge A radial gauge chart has a circular arc, which displays a single value to estimate progress toward a goal.The ggplot2 package is generally the preferred tool of choice for constructing data visualisations in R. The main reason for this is because of its grounding in the grammar of graphicswhich essentially breaks a plot down into a system of fully customisable coordinates and layers, enabling superior design flexibility than the base R graphics.

With ggplot 2, users can produce elegant, professional-looking visualisations that communicate results powerfully to the desired audience. However, ggplot2 runs into some limitations regarding user interactivity. This becomes increasingly problematic when creating interactive documents using R Markdown or dashboard apps in R Shiny, where interactivity is a crucial component of communicating information effectively.

Fortunately, the plotly library significantly enhances the design of interactive charts in R, allowing users to hover over data points, zoom into specific areas, pan back and forth through time, and much more. We start with a simple line chart produced using ggplot2.

The data we are using in our example is anonymous sales and target data between and To begin, simply load the ggplot2 package, then build your plot see ggplot2 cheat sheet for help. This static ggplot2 chart can quickly be made interactive by simply placing it inside the ggplotly function after installing and loading plotly. The static plot has now been brought to life. Users can now zoom, hover, pan and export the plot, and more.

However, the chart still needs some work, specifically the default tooltip the box of information that appears when hovering over a data point.

I want to edit the tooltip to display the information that we want, in a suitable format. Using the scales library, we can define the y axis in a currency format quite easily. I also divided the revenue and target by one million and rounded it to one decimal place, to make the values more readable.

The date can be formatted as desired see here for date formatting options. This plot is now looking good and is fully interactive.

For example, we can zoom into specific points, and pan back and forth through time:. However, we may want to disable or hide some interactive options. Luckily, the plot interactions and mode bar above the chart are fully customisable. In this case, I would like the mode bar to display all the time as opposed to when hovered over and want the option of zooming and panning my plot only, with panning being the default option. First, to define the default interaction, in the layout function we use dragmode :.

To customise the mode bar, the config function is used. Here, the displayModeBar can be set to static to appear all the time, or hover to appear when the cursor is over the plot. The collaborate and displaylogo options are also disabled note: they are removed separately from the modeBarButtonsToRemove function. And then the mode bar buttons to be removed are listed. With that, the original static plot has been converted into an interactive chart, using ggplotly.
