How to use C++ to visualize data to show analysis results?

To use C for data visualization, it is recommended to use the Plotly library. Install and include the Plotly library. Use Plotly::Data to represent data and Plotly::Layout to represent chart layout. Example of creating a line chart: specify x and y values, axis titles, and chart title. Plotly supports other chart types, including bar charts, scatter plots, pie charts, and 3D graphs. Plotly provides functionality to customize graph appearance and interactivity, such as changing axis settings, adding legends and annotations, and enabling interactive operations.

How to use C to visualize data to display analysis results

Data visualization is a method of converting complex data into graphical representations Powerful technology that helps users easily understand and interpret data. There are many libraries in C that can be used to create data visualizations, the most popular of which is [Plotly](https://plotly.com/cpp/).

Data Visualization with Plotly

Plotly is an open source, cross-platform C library for generating interactive and static 2D and 3D graphics. It supports a wide range of chart types, including line charts, bar charts, scatter plots, and more.

To use Plotly, you need to install the library and include it in your code:

#include <plotly/plotly.h>

When creating a graph, you need to provide the data and chart layout. Data can be represented using Plotly::Data objects, and layout can be represented using Plotly::Layout objects.

Practical Case: Creating a Line Chart

The following is an example of using Plotly to create a line chart:

#include <plotly/plotly.h>

int main() {
  // 创建数据
  Plotly::Data data({Plotly::Scatter(Plotly::Scatter::x{1, 2, 3, 4, 5}, Plotly::Scatter::y{1, 4, 9, 16, 25})});

  // 创建布局
  Plotly::Layout layout;
  layout.xaxis.title = "X-Axis";
  layout.yaxis.title = "Y-Axis";
  layout.title = "Line Chart Example";

  // 创建图形
  Plotly::Plotly plot(data, layout);

  // 显示图形
  plot.show();

  return 0;
}

Running this code will create a line chart , where the X-axis represents the x-value and the Y-axis represents the y-value. The graph will have a title and axis labels.

Other Plotly features

In addition to line charts, Plotly also supports many other chart types, including:

• Bar charts
• Scatter Plot
• Histogram
• Pie Chart
• 3D Graph

Plotly also provides many features to customize the appearance of the graph and interactivity, for example:

• Change axis settings (e.g. range and scale)
• Add legends and annotations
• Make the graph interactive (e.g. zoom and pan)

By using Plotly, you can easily visualize your analysis results and create useful charts. This will enable you to communicate your findings to others more effectively.
