The CircularProgressBar allows you to specify an array of colors that will indicate specific ranges of the progress. For example, the CircularProgressBar will be red in the 0%-25% range; orange in the 25%-50% range; yellow in the 50%-75% range; green in the 75%-100% range.
The percentage is an optional feature, since the primary purpose isn't to show a progress value but that something is going on. The percentage text isn't shown by default and wasn't even part of the original idea. Anyway I have been reading some comments from people requesting new features and giving some nice ideas that I've decided to update the control and implement some new features. One of them was this one. The percentage is set through the Percentage property and can be enabled and disabled from the ShowPercentage property. The Text property follows the same reasoning. It wasn't part of the original plan, but as SohjSolwin suggested, it can be useful in some cases, we never know when or where this control will be used. So, from this version on, the control has the ability of drawing both of them like shown below:
When the control is being used to show progress, it is possible to show a message about what is going on and at the same time the progress percentage. Both of them are independent and have different purposes. Even if they are drawn at the same time internally, if I just need to change the value of the percentage, it's easier to do this:
There's nothing more to it. It is particularly useful in situations where the progress bar hasn't made any progress for a long time and we want to pass the message that something is being done. Mainly, it has been fun to program. :)
The Syncfusion Flutter Radial Gauge widget is a multi-purpose data visualization widget. It can be used to visualize different types of data and display the progress of various processes in circular format.
We have already published blogs on different use cases, such as the creation of a speedometer and temperature monitor, using the Flutter Radial Gauge. To continue these use-case series posts, we are now going to create different styles of animated circular progress indicators using the Syncfusion Flutter Radial Gauge.
To get the normal progress bar style, we need to disable the labels and ticks properties in the RadialAxis class and set the axis range values in the minimum and maximum properties based on your design needs.
You can add a pointer to the progress bar by customizing the position and size of the RangePointer class. To show progress, the pointer Value should be updated with a delay action, such as a timer. Then, the pointer value will be dynamically updated by a timer for a specific duration of time. Refer to the following code example.
To add custom content to the center of the circular progress bar in order to indicate the completion of a progression or to convey the current status of it, you can use the annotations feature. To display the current updated progress value, set the pointer value to the annotation text.
To fill the track color, set the axis line thickness to 1, thicknessUnit to GaugeSizeUnit.factor, and the color of the axis line to fill the entire gauge radius. Add the range pointer with the offset position to show the progression.
To fill the progress color, set the range pointer width to 0.95, sizeUnit to GaugeSizeUnit.factor, and the color of the pointer to fill the entire gauge radius. Add an axis line with appropriate thickness to show the track color.
To apply a gradient to the progress bar, set the SweepGradient with its appropriate colors and offset values to the gradient property of the range pointer. Also, add the MarkerPointer and the range pointer and use the same progress value to update both pointers, as shown in the following code example.
You can customize the startAngle and endAngle properties of the radial axis to design full and semi-circular progress bars. To make a semi-circle progress bar, set the startAngle value to 180 and endAngle value to 0, as shown in the following code example.
In this buffer-style progress bar, you can use a secondary progress indicator to denote the primary progression, which is dependent on the secondary progression. This style will allow you to visualize both primary and secondary progressions simultaneously. To add primary and secondary progress pointers, use two range pointers with different progress values.
Design the segmented progress bar by customizing the RadialAxis and the RangePointer. In addition, you need to add one more RadialAxis over the first axis to create the segmented line in the progress bar. The segmented lines are generated by enabling the major ticks for the secondary radial axis with a certain interval and disabling the other axis elements.
In the real-time application, the progress value will be fetched from a service and updated in the pointer. This demo uses a timer to stimulate the progress updates with a duration of 100 milliseconds. The app state will be changed to rebuild the widgets.
I hope you have enjoyed reading this blog and have a clear idea about how to create various styles for a determinate-type circular progress bar. In the upcoming part 2 blog, you can expect some more beautiful styles.
The reported problem occurs due to the showDialog widget of Flutter. The progress value incremented in the periodic timer is not bound to the range pointer value once the radial gauge is loaded using showDialog. We have checked by binding the progress value as the text of the Text widget and in that widget also, the incremented progress value is not getting updated. As this is a flutter framework (showDialog) issue, we will log this in GitHub.
If you search for how to do this, you find me asking on various forums how to do this, and failing to find an answer. And no, I could never get any of the existing control libraries to work with vb.net properly.
I added 2 more control that I want to make for this on the previous reply. I'm open to suggestions for other standard controls. I have had a bit of backtracking to do on this, so only the panels, group boxes, and buttons are working at this time...but as you can see the progress has been better:
The DevExpress WinForms Subscription ships with a fully integrated suite of high-performance data visualization tools so you can deliver intuitive business intelligence dashboards in the shortest possible time. Our WinForms suite includes dozens high impact and fully customizable chart types, maps, interactive gauge indicators, and square/circular treemap controls.
Summary: Wait animations, such as percent-done bars and spinners, inform users of the current working state and make the process more tolerable to the user by reducing uncertainty. Users experience higher satisfaction with a site and are willing to wait longer when the site uses a dynamic progress indicator.
Percent-done progress indicators are the most informative type of wait-animation feedback. They show the current progress, how much has already been accomplished, and how much is left. They convey important information about (approximately) how long the wait time is. This information gives users control (that is, they can decide whether to wait or not); it decreases uncertainty about the length of the process and may reduce the perceived wait time. Progress bars or circles that fill from 0-100% are examples of this type of feedback.
Generally, percent-done progress indicators should be used for longer processes that take 10 or more seconds. A visual indicator that progresses towards completion puts the user at ease and increases their willingness to wait.
A percent-done indicator makes users develop an expectation for how fast the action is being processed. As a result, changes in speed will be noticed and will impact user satisfaction: if the progress moves quickly only to hang on the last percentage remaining, the user will become frustrated and the benefits of showing progress will be negated.
