Hi Aspose.Chart Team,

I have attached an image that shows 2 charts (the first one is the original image and the second one was generated by Aspose.Chart v3.4.6.0 from Roger).

I made a circles and points (1 to 3) on the 2nd chart so I can ask the question more clearly.

My questions are,

1. in the Circle - Point number 1:  How do I hide that line? (ref to the original chart)

2. in the Circle - Point number 2:  How do I hide the "0" value in the X-axis and make the interval value to 2 but the starting value is from 1 (i.e. 1,3,5,..,31) (ref to the original chart)

3. in the Circle - Point number 3:  How do I extend the X-axis line? (ref to the original chart)

This is my code:

         Dim chart As Chart = New Chart()
            Dim s As Series = New Series()

            s.ChartType = ChartType.Bar

            s.CustomAttributes.BarWidth = 5

            s.DefaultDataPoint.Color = System.Drawing.Color.FromArgb(255, 0, 0, 0)
            s.DataPoints.Add(1, 4)
            s.DataPoints.Add(2, 0)
            s.DataPoints.Add(3, 8)
            s.DataPoints.Add(4, 2)
            s.DataPoints.Add(5, 1)
            s.DataPoints.Add(6, 7.2)
            s.DataPoints.Add(7, 1)
            s.DataPoints.Add(8, 6)
            s.DataPoints.Add(9, 4.5)
            s.DataPoints.Add(10, 2.5)
            s.DataPoints.Add(11, 0.6)
            s.DataPoints.Add(12, 32)
            s.DataPoints.Add(13, 3.8)
            s.DataPoints.Add(14, 4)
            s.DataPoints.Add(15, 0)
            s.DataPoints.Add(16, 1)
            s.DataPoints.Add(17, 0)
            s.DataPoints.Add(18, 0)
            s.DataPoints.Add(19, 1)
            s.DataPoints.Add(20, 0)
            s.DataPoints.Add(21, 3)
            s.DataPoints.Add(22, 0)
            s.DataPoints.Add(23, 2.7)
            s.DataPoints.Add(24, 1.9)
            s.DataPoints.Add(25, 22)
            s.DataPoints.Add(26, 3)
            s.DataPoints.Add(27, 3.6)
            s.DataPoints.Add(28, 4.9)
            s.DataPoints.Add(29, 28)
            s.DataPoints.Add(30, 16)
            s.DataPoints.Add(31, 11.6)

            chart.ChartArea.AxisX.IsMajorGridVisible = False
            chart.ChartArea.AxisY2.IsVisible = False
           
            chart.ChartArea.AxisY.DefaultLabel.Font = New System.Drawing.Font("Arial", 6)
            chart.ChartArea.AxisX.DefaultLabel.Font = New System.Drawing.Font("Arial", 6)
            chart.ChartArea.AxisX.Title.Font = New System.Drawing.Font("Arial", 8)
            chart.ChartArea.AxisY.Title.Font = New System.Drawing.Font("Arial", 8)
            chart.ChartArea.AxisX.Title.Text = "Hours of The Day"
            chart.ChartArea.AxisY.Title.Text = "No of Calls"

            chart.ChartArea.AxisX.IsAutoCalc = False
            chart.ChartArea.AxisX.Interval = 2
            chart.ChartArea.AxisX.Minimum = 0
            chart.ChartArea.AxisX.Maximum = 31
            chart.ChartArea.AxisX.IntervalType = IntervalType.Int

            chart.ChartArea.Margin = 4
            chart.ChartArea.Transparence = 255
            chart.BackColor = System.Drawing.Color.FromArgb(255, 255, 255)
            chart.ChartArea().BackColor = System.Drawing.Color.FromArgb(255, 255, 255)
            chart.ChartArea.AxisX.Color = System.Drawing.Color.Black
            chart.ChartArea.AxisY.Color = System.Drawing.Color.Black

            chart.ChartArea.Margin = 0
            chart.ChartArea.MarginLeft = 5
            chart.ChartArea.MarginTop = 10
            chart.ChartArea.MarginRight = 5
            chart.ChartArea.MarginBottom = 2

            chart.ChartArea.AxisX.MajorTickMark.Length = 0

            chart.ChartArea.LegendBox.IsVisible = False

            chart.SeriesCollection.Add(s)

            chart.Height = 184
            chart.Width = 325

            Dim chartBitmap As Bitmap = chart.GetChartImage()

Thank you.

Hi Jarry,

1.   chart.ChartArea.AxisY.MinorTickMark.IsVisible = False

2.   Not supported. We will look into it.

3.   Please using the version attached in Chart generation question (2) thread.

4.   If y value is zero, draws line. This may be a bug. We will close it tomorrow.

Thank you very much Roger

Jarry

Hi Jarry,

Please try the attached fix.

Extending y axis grid and drawing none(y value is zero)  are possible.

About other issue,  x axis lable values start from 1 to 31,  it is complex and  we could not supported in a short time. here is a simple solution.

            chart.ChartArea.AxisX.IsAutoCalc = False
            chart.ChartArea.AxisX.Interval = 2
            chart.ChartArea.AxisX.Minimum = 1
            chart.ChartArea.AxisX.Maximum = 31
            chart.ChartArea.AxisX.IntervalType = IntervalType.Int

Thank you very much Roger.

As always, it works Great!

it's nearlly there..

btw, if I used the work around to hide the "0" value in the x-axis lable, the graph doesn't display properly.

I am just wondering, do you have an ETA for solving this issue in the next version release? because I really need this graph requirement for my app production release.

Thank you very much Roger for all your helps and supports.

Best regards,

Jarry

Hi Jarry,

Ihave added the feature to our task list. but it is complex and now i cann't tell you what time is to solving it. We will provide a new version as soon as possible that may be about a month.

Thank you.

Thank you very much Roger for all your Helps.

i'll check the updated Aspose.Chart API again in one month.

But if you have solved it before one month, could you please let me know via email so i can test it.

Once again, Thank you.

Regards,

Jarry

Okay, if we hava solved it, i attach new version release here first and mail to you.

Thank you.

Thank you Very Much Roger.

Jarry

Hi Jarry,

I have checked Aspose.Charts source code and found a way to satisfy your requirement in current version. But the way requires us to place the code at last, otherwise there has a catastrophic error or the code does not work.

Here's the codes:

            ......

            chart.SeriesCollection.Add(s)

            chart.Height = 184
            chart.Width = 325

            Dim i As Integer
            For i = 0 To 30 Step i + 2
                chart.ChartArea.AxisX.AxisLabels(i).IsVisible = False
            Next

            pictureBox1.Image = chart.GetChartImage()

And modifys AxisX.Interval to 1

            chart.ChartArea.AxisX.IsAutoCalc = False
            chart.ChartArea.AxisX.Interval = 1
            chart.ChartArea.AxisX.Minimum = 0
            chart.ChartArea.AxisX.Maximum = 31
            chart.ChartArea.AxisX.IntervalType = IntervalType.Int
