I have one data table with column X and Y, fit Y by X.

I only what to get the fit results like the coefficent and the intercept without drawing a chart.

who knows how to do it?

Use the Fit Model platform, rather than the Fit Y by X, and using the options under the Red Triangle, you will be able to unselect all of the unwanted components, including the plot

Another option to separate the parameter estimates from the report is to right click anywhere in the Parameter Estimates and select "Make into Data Table"

Re: How to get the bivariate regression results without plot the chart

Another option is to launch the analysis in "invisible" mode and then query the report for the values you want to extract using display box subscripting:

biv = Bivariate( Y( :weight ), X( :height ), Fit Polynomial(2), Invisible);

rep = Report(biv);

//all = rep["Parameter Estimates"][TableBox(1)] <<Get As Matrix;

pe = rep["Parameter Estimates"][Number Col Box("Estimate")] <<Get As Matrix;

biv << Close();

show(pe);
