C# 如何动态填充图片框

我最近开始学习c#编程。我正在尝试使用windows窗体应用程序创建GUI。 我需要更新图片瓶与不同的颜色根据一些条件。我从电子板上得到四个传感器的读数，它们是温度、压力、密度和体积。基于这些值，我必须更新图片瓶。我设计了windows窗体，如下所示。 我为四个传感器读数创建了四个复选框。最初，我手动输入预期转移体积，并将该值设置为图片瓶上的最大刻度。使用温度、压力、密度复选框来估计体积中存在的数量。要估算体积，用户可以使用温度传感器或密度传感器，或者全部使用，或者仅使用两个。如果我单击一个复选框，则我将仅使用该传感器的读数。卷的复选框表示获取到目前为止传输的卷的数量。 我有这样的条件来估计数量

1)Liquid 
 Temperature = 0 to 30 c
 Pressure =    0 to 200 bar
 Density  = 0.5 to 0.95 g/cc.
2)Gas
 Temperature = 31 to 60 c
 Pressure =    201 to 400 bar
 Density  =    0 to 0.5 g/cc.
3)Water
 Temperature = 61 to 90 c
 Pressure =    401 to 600 bar
 Density  =    0.956 to 1,15 g/cc.
4)Oil
 Temperature = 91 to 120 c
 Pressure =    601 to 800 bar
 Density  =    1.2 to 1.35 g/cc.
5)Mud
 Temperature = 121 to 150 c
 Pressure =    801 to 1000 bar
 Density  =    1.15 to 1.3 g/cc.
6)Not identified
 all the conditions failed.

程序是，如果我勾选了所有三个传感器复选框，那么我将使用三个传感器读数，并检查此条件以及任何满足条件的情况，然后用颜色填充瓶子。我将得到目前转移的数量，并检查这些条件，然后在图片瓶中填入关于颜色的数量。当我手动输入值时，我有绘制图片框的代码，但与使用传感器值和条件不同

    private void DrawPercentages(int[] percentages, Color[] colors, float[] volumetransfer)
    {
        Bitmap bmp = new Bitmap(pictureBox1.Width, pictureBox1.Height);
        Graphics G = Graphics.FromImage(bmp);
        // Create a Graphics object to draw on the picturebox
        //Graphics G = pictureBox1.CreateGraphics();

        // Calculate the number of pixels per 1 percent
        float pixelsPerPercent = pictureBox1.Height / volumetransfer[0];

        // Keep track of the height at which to start drawing (starting from the bottom going up)
        int drawHeight = pictureBox1.Height;

        // Loop through all percentages and draw a rectangle for each
        for (int i = 0; i < percentages.Length; i++)
        {
            // Create a brush with the current color
            SolidBrush brush = new SolidBrush(colors[i]);
            // Update the height at which the next rectangle is drawn.
            drawHeight -= (int)(pixelsPerPercent * percentages[i]);
            // Draw a filled rectangle
            G.FillRectangle(brush, 0, drawHeight, pictureBox1.Width, pixelsPerPercent * percentages[i]);
        }
        pictureBox1.Image = bmp;
    }

请帮我完成这项任务

任务是我将从体积复选框中获取体积数量，所以我需要在图片瓶中填充那么多数量。考虑到上述条件，总量为液体、气体、水或其他。例如，我从体积传感器读取“50”，然后我应该用颜色将图片瓶更新到50（刻度）。同时，哪种颜色是由上述条件决定的。我将得到温度、压力、密度值，我需要检查是“气体”还是“液体”或“水”。满足任何条件后，用该颜色填充至刻度“50”

我试过这样做

        public void DrawVolume(double volume, VolumeTypes volumeType, PictureBox pictureBottle)
    {
        ucSample sample = new ucSample();

        Color color = pictureBottle.BackColor;

        switch (volumeType)
        {
            case VolumeTypes.Gas: color = Color.Lime;
                break;
            case VolumeTypes.HydrocarboneLiquid: color = Color.Red;
                break;
            case VolumeTypes.Water: color = Color.Blue;
                break;
            case VolumeTypes.WaterBasedMud: color = Color.SaddleBrown;
                break;
            case VolumeTypes.OliBasedMud: color = Color.Chocolate;
                break;
            case VolumeTypes.NotIdentified: color = Color.Gray;
                break;

        }
        Bitmap bmp = new Bitmap(pictureBottle.Width, pictureBottle.Height);
        Graphics G = Graphics.FromImage(bmp);

        float pixelsPerPercent = (float)(pictureBottle.Height * (volume / ucSample.Volume));

        int drawHeight = (int)volume;
        SolidBrush brush = new SolidBrush(color);
        G.FillRectangle(brush, 0, drawHeight, pictureBottle.Width, (int)(pixelsPerPercent * volume));
        pictureBottle.Image = bmp;

    }

我在上面的代码中尝试的是：我将三个参数传递给“DrawVolume”方法，其中“volume”参数是我要在图片框中填充的值。“volumeType”是关于该卷的颜色。图片框的“ucSample.Volume”比例

上面的代码不是我想要的。这不是我想要的。 例如，我的图片框的比例是从“0到100”，我的“体积”是“50”，然后它必须从“0到50”绘制，但上面的代码绘制的比“0到60”更多。我不知道为什么会这样。我是否在“drawheight”中使用了错误的计算方法
