Max value of chart

[GyllionElderen]

Hello there, I'm using Microchart for Xamarin.Forms. Great tool so far! However, I found an interesting bug:

According to the tutorial, the max value will become the value of the chart with the highest value. In my case, the max value of the chart is that divided by 2. If I increase the 'MaxValue' property to 400, it still does not give me the desired max value.

Is this a known bug? Am I doing something wrong in my code? Please let me know. I'm using 0.8.1-pre.

Could you provide your chart initialization code? Not sure to understand your case...

If you define chart.MaxValue = 400, then your February column should be filled. Now if you define chart.MaxValue = 800, then your February column should be half filled (like on your screenshot) and so on.

And by default the MaxValue is the maximum of all your entry values (here 400).

Even if I put the MaxValue to 400, still no result. This is the code I was using:

return new BarChart
{
    Entries = new List<Entry>
     {
         new Entry(200)
         {
            Label = "January",
            ValueLabel = "200",
            Color = SKColor.Parse("#266489")
         },
         new Entry(400)
         {
             Label = "February",
             ValueLabel = "400",
             Color = SKColor.Parse("#68B9C0")
         },
         new Entry(100)
         {
             Label = "March",
             ValueLabel = "-100",
             Color = SKColor.Parse("#90D585")
         }
     },
     LabelTextSize = 30,
     BarAreaAlpha = 255,
     MaxValue = 400
 };

Okay, spotted the error.

I apologize, I'll publish an update very soon. :(

[GyllionElderen]

Okay, I found out what the problem was. The animation was not working properly. For a temporary fix, try this:

BarChart barChart = new BarChart{ IsAnimated = false };

[aloisdeniel]

Sad that you can't use animation.

I just published a new pre-release which include a fix related to MaxValue.

Is it better now?

[GyllionElderen]

I installed the new pre-release and the problem is still there. I figured that the animation cannot play. When loading is done, it shows only the current frame as following:

Do I need to enable something in my project in order to make the animation play?

Some news about the maxVlaue? i'm trying to use it with Donut, to show something like:
maxValue = 100%, achieved= 80%, so the graphic fill just 80% of the donut.

[aloisdeniel]

Hum, the use of RadialGaugeChart is more appropriate in this case for me.

Setting a max value to a donut doesn't make sense to me, imagine your have 2 portions with 60 and 50and a max value of 100 ? Do we have to cut the last portion ?

[Calvin-2DWeb]

that's right, I was trying to use the wrong chart. and if I need to use in Donut form, I just need to use two portions one with the rest of the other, (100% = 1 portion of 80 and other of 20) this will made the chart I need. Thanks!
And a tip: Microcharts is awesome, but maybe it need more documentation, like what attributes and functions each chart have and so on... (if there is a documentation for that, I apologize, because I didn't find)

[Calvin-2DWeb]

Also, there is a Way to show in the chart the MaxValue as a Label or something?

Closing due to inactivity and apparent resolution. @CalvinNunes if you wish to know about the maxValue label as an option, please start a new issue.
