 Number Scaling Number scaling lets you define your own scales for numbers and then apply it to all numbers on the chart. Basic Example Let's start with the most basic example which is already defined in FusionWidgets XT - thousands and millions scale. If your numbers on the chart are greater than 1000, FusionWidgets XT gives you the option to scale them to K (Thousands) or M (Millions). For example, if you plot an angular gauge with dial values as 3400 and 17400 and use number scaling by setting , you'll see the following chart: As you can see above, FusionWidgets XT has scaled the numbers down to K. By default, FusionWidgets XT has the K,M (1000,1000) scaling defined for each chart. You can, however, change it to anything you wish. Let's see it in the next example. Adding billions to default scaling FusionWidgets XT, by default, has 1000,1000 (K,M) scaling defined for all charts. It doesn't have the scaling for billions defined. Let's modify the number scaling to add billion so that the final scale looks like 1000,1000,1000 (K,M,B). This scale, in human terms, will look something as under: 1000 = 1 K 1000 K = 1 M 1000 M = 1 B Now, to convert this scale into FusionWidgets XT XML format, you'll have to do the following: Define your own scale for the chart as under: If you carefully see this and match it with previous table, you'll find that whatever numeric figure was present on the left hand side of the table is put in numberScaleValue and whatever unit was present on the right side of the scale table has been put under numberScaleUnit - all separated by commas. Set the chart formatting flag to on as under: When you now view a chart containing data in billions, you'll see as under. Note that the chart now contains figure both in millions and billions. The XML/JSON for the above chart is: ```                                                                  ``` ```{ "chart": { "lowerlimit": "0", "upperlimit": "2000000000", "lowerlimitdisplay": "Bad", "upperlimitdisplay": "Good", "numberscalevalue": "1000,1000,1000", "numberscaleunit": "K,M,B", "formatnumberscale": "1" }, "colorrange": { "color": [ { "minvalue": "0", "maxvalue": "1000000000", "code": "FF654F" }, { "minvalue": "1000000000", "maxvalue": "1400000000", "code": "F6BD0F" }, { "minvalue": "1400000000", "maxvalue": "2000000000", "code": "8BBA00" } ] }, "dials": { "dial": [ { "value": "340000000", "rearextension": "10" }, { "value": "1740000000", "rearextension": "10" } ] } }``` Another Example - Putting time in scale Let's consider another example where we intend to plot time related figures on the chart. Say we're plotting a chart which indicates the time taken by a machine to do a particular task. The task can take any time ranging from a few seconds to few days. And we've the data for the task in seconds itself. Now, if we were to show all the data on the chart in seconds only, it won't appear too legible. What we can do is build a scale indicating time and then specify it to the chart. This scale, in human terms, will look something as under: 60 seconds = 1 minute 60 minute = 1 hr 24 hrs = 1 day 7 days = 1 week Now, to convert this scale into FusionWidgets XT XML format, you'll have to do it as under: First you need to define the unit of the data which you're providing. Like, in this example, you're providing all data in seconds. So, the default number scale will be represented in seconds. We can represent it as under: Next, we define our own scale for the chart as under: Again, if you carefully see this and match it with our range, you'll find that whatever numeric figures are present on the left side of the range have been put in numberScaleValue and whatever units are present on the right side of the scale have been put under numberScaleUnit - all separated by commas. Set the chart formatting flags to on as under: The entire XML/JSON looks as under: ```                                      ``` ```{ "chart": { "lowerlimit": "0", "upperlimit": "100000", "numberscalevalue": "60,60,24,7", "numberscaleunit": "min,hr,day,wk", "formatnumberscale": "1" }, "colorrange": { "color": [ { "minvalue": "0", "maxvalue": "100000", "code": "F6BD0F" } ] }, "dials": { "dial": [ { "value": "340", "rearextension": "10" }, { "value": "17400", "rearextension": "10" } ] } }``` When you now view the chart, you'll see that all the data has been automatically scaled to the best value. Like: 100000s - the upper limit was converted to 1.16 days 340s - the 1st dial's value was converted to 5.67 min 17400s - the 2nd dial's value was converted to 4.83 hours and so on... Storage Size Example Take another example, where you're plotting a chart indicating memory usage of a network server. The usage can be from few bits to a few gigabytes. Again, you've all your data in bits - so we can render the range as under: 8 bits = 1 Byte 1024 bytes = 1 KB 1024 KB = 1 MB 1024 MB = 1 GB 1024 GB = 1 TB And the XML can be written as under: Length/Distance Example Let's consider another length/distance example. The standard length/distance range can be rendered as under (with inches being the default unit): 12 inches = 1 feet 3 feet = 1 yard 1760 yards = 1 mile So, we can write the XML as under:
