我有一个图表,其中日期(字符串)作为 X 值,小数作为 Y 值。我想放大图表,但设置时:
chart1.ChartAreas[0].CursorX.IsUserEnabled = true;
chart1.ChartAreas[0].CursorX.IsUserSelectionEnabled = true;
chart1.ChartAreas[0].AxisX.ScaleView.Zoomable = true;
它在 X 轴上放大到间隔 1。我想在轴上逐渐放大,但是当我设置\
chart1.ChartAreas[0].CursorX.Interval = 0.1;
(除 1 之外的任何内容)X 轴上的标签消失。有人可以帮我吗,我是图表控件的新手。请原谅我的无知。任何建议将不胜感激到目前为止,这是我的一段代码:
chart1.ChartAreas[0].CursorX.IsUserEnabled = true;
chart1.ChartAreas[0].CursorX.IsUserSelectionEnabled = true;
chart1.ChartAreas[0].AxisX.ScaleView.Zoomable = true;
chart1.Series[0].IsVisibleInLegend = false;
chart1.Series[0].ChartType = SeriesChartType.Area;
DateTime sday = Convert.ToDateTime(earnings1.dataGridView1[0, 0].Value.ToString());
chart1.Series[0].XValueType = ChartValueType.String;
int i = 0;
chart1.Series[0].SmartLabelStyle.Enabled = false;
foreach (DataGridViewRow dgvr in earnings1.dataGridView1.Rows)
{
decimal testing = Convert.ToDecimal(earnings1.dataGridView1[1, i].Value);
testing = decimal.Truncate(testing);
var point = new DataPoint(i + 1, Convert.ToDouble(testing));
point.Label = testing.ToString();
point.Font = new Font("Century Gothic", 8, FontStyle.Bold);
chart1.Series[0].Points.Add(point);
chart1.Series[0].LabelAngle = -90;
chart1.Series[0].Points[i].AxisLabel = sday.ToString("dd/MM/yyyy");
sday = sday.AddDays(1);
i++;
}
